Without saying too much:
Seems to be a spate of DDOS against UK based voip providers at the
moment. For ransom. Don't pay.
One provider said that traditional approaches did not work. They tried
Voxility but just got false positives. There are providers that do work.
But in the UK a lot of traffic goes over peers through internet
exchanges. So just swapping transit only half the problem.
Prep wise:
So practice altering your IP advertisements, dropping and bringing up
peers. If you connect to route servers, practice doing selective
announcements. Try to get private interconnects to your upstream telco
providers. Get your network teams warmed up for when it does
happen. If you host with a cloud provider, have a backup because if
DDOS is coming from the same cloud .....
