SORBS – back soon

If you’ve tried to get an address delisted from SORBS this week you’ll have found that their site is degraded, and there’s no way to request delisting.
They’ve been dealing with some very nasty database / hardware problems and while they’re fixing those the externally visible SORBS services are running in a read-only mode (where the list is published, but IP addresses can’t be added or removed).
The migration to new infrastructure is going well, and unless something unexpected happens I’d guess they’ll be running normally some time tomorrow.

This comedic interlude is about the “DDoS” – a distributed denial of service attack. What is a denial of service attack?
