We are currently experiencing an issue with one of our XenServer hosts that is affecting a number of customer virtual machines.

We are working to resolve the issue at the moment. Please accept our apologies for any inconvenience.

Update 07:13 All customer virtual machines are now back online. We are looking into the cause of the unexpected reboot of the host.

Unfortunately it has not been able to immediately recover the XenServer host that was upgraded this evening.

To ensure that remaining customer virtual machines can get back online we are going to add additional RAM to the other hosts in the pool. This will result in all virtual machines experiencing a small amount of downtime.

We apologise for any inconvenience caused.

Update 01:13: Around 60% of customer virtual machines are now back online; we are still working on the rest. We are aiming to get all virtual machines back online by 02:00 and thank you for your patience.

Unfortuantely we are experiencing an issue with the XenServer host that has been upgraded relating to the Flash storage used to boot the host, we are currently working to resolve this.

Most customer machines remain online but the small number of servers that were shut down may experience downtime beyond the two hour maintenance window whilst we resolve the issue.

Please accept our apologies for any inconvenience caused.

Scheduled Maintenance: XenServer host memory upgrade

We will be performing scheduled maintenance to upgrade the memory in one of our XenServer blades to improve the specification. Most customer virtual machines will migrated to other hosts before this upgrade, but a small number of virtual machines will need to be shut down for around half an hour - we will be contacting those customers affected individually.

All other virtual servers will remain online and unaffected, although all services are at risk during this period due to reduced redundancy and live migration required to move virtual machines off the host being upgraded.
