zerigo is under DDOS
"UPDATE 2:08am PST/9:08am GMT: Zerigo tweets “We really apologize. We are working hard to get everything back to normal. No ETA yet”."
Our a, b and d.ns.zerigo.net nameservers are currently under high load due to a DDOS attack.
Update
We are now seeing reduced load after applying filters for the specific type of queries present in the DDOS.
Update
We have filters on 90% of the DNS infrastructure. We are working with our carrier in the UK to lift null routes they've placed to mitigate the impact of the DDOS.
Update
DDOS packets continue to arrive. So far we are seeing the origins of this traffic almost mostly in Europe. We will have a.ns.zerigo.net back online in the morning hours eastern time.
