At 2025-03-05 14:39 there was a brief outage to IMAP email services. No other services were affected. This appears to have been caused by an unexpected power event in the Netherlands datacenter.
All services are back online, and there was no data loss.
If you are still experiencing login issues with IMAP, please raise a support ticket.
Update: There is a fault with a memory module in one of the servers. There will be a 20 min service outage affecting some (IMAP only) email services at 1900 GMT tonight.
Update: The maintenance is complete.
