The data centre informs us that connectivity on their network was restored at 09:24 UTC.
We have been able to confirm this by accessing all of our servers in this data centre:
- Incoming mail is once again being processed immediately by server NC027, although any incoming mail sent during the disruption may be delayed a little longer until the sending mail servers try again. This is not under our control.
- Server NC023 is also processing email immediately.
We apologise for this interruption. Denial of service attacks (especially distributed denial of service attacks) are extremely difficult and expensive to fight. We have confidence that the data centre did everything they could as quickly as they could to combat this attack.
