Yesterdays system administration efforts were an unprecedented disaster and caused a significant unplanned downtime, for which we sincerely apologise.
It had been intended to move a couple of unrelated web sites from the server that runs DearDiary, to another server. However, for some odd reason, which is still as yet unknown, doing so caused the failure of the DearDiary server with some very strange effects.
No data was lost.
In the end, the system was restored by re-adding the other sites back to the DearDiary server… We will try again another day, with a bit better plan.
Apologies for the downtime.
