Due to a failing disk which significantly reduced database performance to only a few kilobytes per second our cluster has been finding it difficult to sync important data between nodes starting from mid day yesterday to early this morning. We did detect and correct this behaviour by taking the affected node offline and installing a replacement disk drive.

At no time were queries affected as all data accessed there is done so from memory for performance reasons. But new account creation, account changes such as adding/removing whitelist/blacklist entries were significantly delayed due to the slow syncing performance caused by the degraded disk.

We apologise to all customers that were inconvenienced by this problem, we should have taken the affected server offline sooner and we would have except it wasn't quite obvious to us at the time why the server was not syncing at the speed we expect it to.

Thank you.
