This is now back online - the chassis has been replaced, and we will continue to monitor the server / logs to ensure the issue is resolved entirely.
We have noticed intermittent issues being reported on our monitoring suite over the past 48 hours, which have indicated a potential hardware issue.
We replaced the drives in the machine, as we noticed ata6 related errors being reported, which indicate an issue with either the disks themselves, or the cabling.
This particular machine has no visible cables, and are instead directly in the bays on the chassis. As such, a replacement machine has been built as an emergency replacement to prevent further outages.
The disks are currently being moved to the new machine, and the network configuration is also being amended.
The overall outage is expected to last around 20 - 30 minutes, however due to the complexity of the task, we of course appreciate your patience whilst this is carried out.
Meanwhile, if you have any questions, do let us know although please expect a slight delay in response, due to the team being tied up resolving the issue currently.
We are investigating potential hardware or kernel related issue with Bravo at present.
We are aware of the outages, and apologies for the inconvenience caused - we will be working on this with the highest priority.
