There are still a number of disks stuck on the tail that have yet to complete migration. We have taken some remedial action that seems to have improved performance a small amount but issues continue

Whilst the majority of migrations have now completed there still remains a small number of disks that have failed to migrate overnight. We will be attempting remedial action to complete the migration of these discs off the tail.

Migrations continue off the tail but due to the nature of the issue they are taking a lot longer than normal.

We're hoping that all migrations will be completed by tomorrow, the tail will then be taken out of service so we can identify and correct the issue.

Migrations are continuing but due to reduced storage throughput this is taking a lot longer than would be expected.

We have confirmed an issue with the storage on tail55, we've managed to get it into a state where we are able to start migrating discs off the host, this is now in progress.

We're investigating an issue with BigV tail55.

You might be affected if your VM disk is currently running on tail55.

Sorry about this! We're investigating and working to restore full service as soon as possible. We'll post updates here.

If you're experiencing any problems with your services at Bytemark that you think might be related, please do get in touch.
