SH2 Disk Error
June 22, 2011 12:47 UTC (closed)
SH2 is currently showing a disk error on one of its hard drives which is stopping some accounts from being available. We will be rebooting the server shortly so that we can repair the error, during which the server will be unavailable. We're estimating that this will take 15-30 minutes.
Our network provider will be performing maintenance on their backbone network. This shouldn't cause any disruption, but customers may briefly experience slightly degraded network performance.
This work is planned for the following dates:
- Saturday, June 18, 0600 - 1000 UTC
- Sunday, June 19, 0600 - 1000 UTC
Nameserver IP address changes
The IP addresses of our three nameservers are changing. You don't need to do anything if you've registered your domain name through us, but if you've registered it elsewhere you might need to let your domain registrar know about the change.
If your domain isn't registered through us, you should make sure that you update your nameservers to the following:
The old nameservers will be active until at least the end of April, but we recommend that customers switch to the new servers as soon as they can to avoid any possible disruption.
Django Security Update
The Django developers have released a security update for Django, which we will be installing this Friday (February 19, 2011). This update contains some backwards-incompatible changes; if you're using Django please see the release notes to find out if this will affect you:
Fantastico installation errors
It is currently not possible to install new scripts using the Fantastico option in cPanel. This is due to a bug in Fantastico triggered by last week's cPanel update. We're currently looking into ways to work around the bug.
Any customers who would like to install a new script via Fantastico but are unable to do so should contact our support team and we'll be happy to manually install it for you.
Existing script installations are not affected.
SH2 Hard Disk Issues
January 14, 2011 14:29 UTC (closed)
We will be performing maintenance on SH2 immediately in order to fix a hard disk error. We believe we should now be able to perform this maintenance without taking the server down, so there shouldn't be any disruption while we do this.
We are also investigating a separate problem which is causing some users' home directories to be inaccessible. This will be causing a variety of errors for the affected users and we hope to have this fixed soon.
We will be rebooting all three servers this Friday, January 14, 2011 starting at 1300 UTC in order to apply a software update. Each server will be unavailable for approximately 10 minutes while it's rebooted.
sorl-thumbnail With Python 2.4
Customers who are using sorl-thumbnail with Python 2.4 may see an Unhandled Exception error in their Django applications. This is due to a change in the latest version of sorl-thumbnail which makes it incompatible with Python 2.4.
Customers can get around the problem by using Python 2.6 instead. To do that, simply change the first line of your django.fcgi file to the following:
Our network provider will be performing network maintenance on Saturday, November 13, 2010 between 0600 UTC and 1100 UTC. They do not expect this to cause any disruption to service, however there is a small chance that some network traffic could be affected for brief periods.
We've just experienced what appears to be a brief network outage, affecting customers in Europe. This seems to have affected people trying to reach both our web site and customer web sites, which suggests that there was a wider network issue affecting multiple providers (our site is on a separate network from customer sites to try to avoid communication problems in the event of an outage).
Our network provider has acknowledged the issue, and we will update this notice when we have more information, though at this time everything appears to be back to normal.
Following the successful upgrade of SH3 this week, we will be upgrading SH1 and SH2 on Wednesday, October 13, 2010 beginning at 0600 UTC. Barring any problems, we expect each server to be offline for approximately 15-20 minutes each while new hardware is installed.
Regular Maintenance Window
We’ve scheduled a regular weekly maintenance window for Fridays, between 12:00 (noon) and 16:00 (UK time). Any work which we don’t expect to disrupt our services will be performed during that time, without a specific announcement being sent out. Anything that might cause a disruption will still be announced via service notice (but will probably be performed during that same maintenance window as well).
Please see our blog for more details: <http://valca.to/maint>
Internal Server Errors
Earlier today we made a change which requires some modifications to some .htaccess files. We attempted to make these modifications automatically, but it seems that some files were missed out. We're working on modifying the files which were missed out, but in the meantime you can fix any of your own files by removing the "FollowSymLinks" option.
Django Admin Media
We've made a change to our server configuration for security reasons which may affect any customers using Django. If you make use of the admin application which is included as part of Django, and you have set your ADMIN_MEDIA_PREFIX to anything other than "/admin-media/" this might affect you. If you are already using that prefix, then you can disregard this notice.
It is no longer possible to access the Django admin media via a symbolic link, but we have configured the server to always serve the admin media files at "/admin-media/" without a symbolic link being present. This means that if you currently use a symbolic link to access the admin media files, you have two choices:
- Change your ADMIN_MEDIA_PREFIX setting to "/admin-media/".
- Copy the "/usr/lib/python2.4/site-packages/django/contrib/admin/media/" directory to a location of your choice.
Any customers requiring assistance with this change should open a support ticket by logging into your Valcato Account.
We are currently investigating extremely high loads on SH2 and SH3, which is affecting server availability.
Software Updates (July 2010) - Includes reboot
We'll be performing routine software updates on all three servers on Tuesday, July 13, 2010, beginning at 1400 UTC. We will need to reboot the servers at the start of this work, meaning each server will be unavailable for approximately ten minutes. We do not anticipate any other down time, though visitors may notice that web pages load a little slower than usual while this work is carried out.
Software Updates (June 2010) - Includes reboot, Django 1.2
We will be performing routine software updates on Sunday, June 13, 2010 starting at 1500 UTC. This will include one update which will require the servers to be rebooted during which time all services will be unavailable -- this typically takes ten to fifteen minutes for each server.
We will also be updating Django to version 1.2.1. Customers who use Django should review the Django 1.2 release notes at <http://valca.to/django12> as this update includes backwards-incompatible changes. Any customers who need to stay on Django 1.1 can install their own copy of Django in their home directories -- customers who would like assistance doing this should contact us before Friday, June 11, 2010 and we will be happy to install it for you.
Secure FTP Connections Required After June 8th
Customers who use FTP to upload files to their web sites will be required to connect using SSL/TLS from June 8, 2010. This is an important security measure to prevent passwords being compromised by eavesdroppers. Most modern FTP clients should support this kind of connection, and it should just be a case of selecting the appropriate option in the software.
Customers who currently use an FTP client which does not support encrypted connections should consider one of the following free FTP clients:
Customers can also use SSH, WebDisk or the cPanel file manager instead of FTP.
Software Updates (May 2010) - Includes major cPanel update
We will be installing software updates on Monday, May 3, 2010 starting at 1400 UTC. This includes an operating system update which will require the servers to be rebooted, meaning they will be temporarily unavailable for approximately ten minutes.
We will also be updating cPanel to version 11.25, which includes many new features and improvements which our customers should find useful. (Details of the new features will be posted to our blog after the update is performed.) Because of the size of this cPanel update, it will take much longer than normal for everything to be installed. We don't currently have an estimate for how long this will take, but we will post updates to this notice while we work.
Reboot for security update
We will be rebooting all three servers for a security update, tomorrow starting at 1500 UTC. Each server will be unavailable for approximately 10 minutes.
Software Updates (February 2010)
We will be performing our routine monthly software updates on Thursday, February 11, 2010 at 1000 UTC. There should be no disruptions to services during this work.
Reboot for Security Update
We'll be rebooting all three servers tonight starting at 2200 UTC in order to apply a security update. Each server will be unavailable for approximately 10-15 minutes.
Advance notice: PHP 5.3 and Magic Quotes
This is advance notice that soon we will be updating PHP to the latest release of PHP 5.3 (we currently run the latest release of PHP 5.2). PHP 5.3 is not fully compatible with code which was written for PHP 5.2, so it is important that you make sure any PHP scripts you're using will work with PHP 5.3 before this update is performed -- in most cases people will find that their scripts are already compatible, but we strongly advise all customers to make sure that this is the case for them. A full list of the incompatible changes in PHP 5.3 can be found at: <http://valca.to/php53>
We will also be disabling PHP's Magic Quotes feature at the same time, as this feature has been deprecated by the PHP developers and is due to be removed completely in a future release. For now, customers who still need this feature can re-enable it by following the instructions for creating a custom php.ini file at <http://valca.to/phpini> -- however, we recommend against relying on the Magic Quotes feature where possible.
A precise date and time for these changes will be announced closer to the time, but this is provisionally scheduled for the afternoon of March 13, 2010.
Software Updates (January 2010)
We will be performing our routine monthly software updates on Saturday, January 9, 2010 at 1500 UTC. There should be no disruptions to services during this work.
Reboot for Security Update

Slow page loading on SH2
September 9, 2009 21:04 UTC (closed)
Some users on SH2 may have noticed that at times their web sites have been loading more slowly than usual. We have made some configuration changes to improve the performance of the HTTP server under increased traffic, and we're monitoring the server's performance to ensure that this issue is resolved.
Software Updates (September 2009)
We will be performing regular software updates on Saturday, September 12, 2009 from 1300 UTC. We are not expecting there to be any down time during this work, however it is possible that some services could be unavailable for brief periods.
We'll shortly be rebooting both servers in order to apply a security update. SH1 will be rebooted at 1600 UTC and SH2 will be rebooted at 1615 UTC (a little under two hours from now). Each server will be unavailable for approximately ten minutes.
Both servers will be rebooted shortly in order to apply a security update. SH1 will be rebooted at 1900 UTC and SH2 will be rebooted at 1915 UTC today (20-35 minutes from now). This will take approximately ten minutes, during which time services will be unavailable.
We are currently experiencing a total network outage affecting both of our servers. Updates will be posted as soon as we have more information.

Other services may also be unavailable for brief periods while updated software is installed.
We will add updates to this service notice during this maintenance.
We will be applying an operating system update to all of the servers which host our customers' web sites; this will require the servers to be rebooted, which will result in a maximum of ten minutes down time for each server.
This will be performed starting at 15:00 UTC on Friday, January 23, 2009. Our billing and support systems will not be affected.
