Overnight Storage [Resolved]
One of the storage servers still hadn't mounted after last nights power breaker failure despite appearing that it had. As a result those of you with email on this server have been unable to access your email from 20:36 last night until 08:15 this morning.


We sincerely apologise for this further outage, this is the 4th week in a row we've suffered some sort of hardware failure that has affected the service and we're seriously considering all available options. Up until now this simply included new machines built with dual power supplies and feeds but discussions are now including moving to a new datacenter provider as years of trust have been wiped out with the constant stream of failures that have been outside of our control.

Brief Outage [Resolved]
20:36 - 20:42
Brief outage caused by 8 servers all appearing to loose power at the same time despite being on battery/generator backups in case of failure. Currently investigating with datacenter the exact cause.


20:55
One of the storage servers isn't responding, some of you will be unable to login at the current time as a result. Should have it online in a few minutes.


20:56
Storage remounted, service fully online. Still determining original cause of the outage.

22:57
Datacenter has confirmed that a faulty power breaker tripped and had to be replaced with an on-site spare. Power was down for under 5 minutes but it took a few further minutes for the servers to boot back up. As you know we have been investigating A/B power feeds to prevent any single power fault from taking down the service.

Datacenter Power Failure [Resolved]
19:37 - Power circuit failed in the datacenter, knocking out 3 servers. Service was slow as two of the servers were webservers, leaving web access restricted in speed. Client access and inbound email are both unaffected as no mail servers were on the failed circuit.


20:07 - All affected servers back online, web access stabilising across the webservers. Service may be a little slow for the next 10-15 minutes as users online are redistributed over available webservers.
