Is now. If you look at their BGP announcements over the last week using 
something like bgplay you can see them move all their prefixes behind 
cloudflare.

Bandwidth.com is using cloudflares magic transit for DDOS protection. Seems to 
be working ok. CF says it doesn’t matter the protocol they can scrub the 
traffic.

A WAF doesn't mean much to SIP, IAX2, RTP, etc. 




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 .....
