Do we know this is a SIP/RTP targeted volumetric attack and those arent
just collateral damage in a more plebian attack aimed ad portals/apis or
routers?
I can understand them being tight lipped but some transparency helps the
situation.
I wonder if DHS is involved yet?

The reality is probably that the DDoS attack is now so big, they
can’t handle it on their own, so they’re scrambling to contract out
with another provider who can handle it. That would explain why the
BGP routes they advertise have shifted. These DDoS products typically
take weeks to setup, so they’re likely having to scramble. I’ll be
surprised if this does NOT continue tomorrow (unfortunately).
From my understanding this is not your typical volumetric DDoS but
something specific to SIP or VoIP and thus the typical scrubbing
services aren't going to be effective against the voice side of things.
Obviously they are keeping things close to the vest in order not to
give too much information to the bad guys but I agree that it may take
some time to resolve.

Generic SIP client here, and the ongoing "continue to investigate"
notices are infuriatingly like "we have no damn clue what we're
doing." Try explaining to customers why it's not "our fault*" and
that there's no way to estimate a repair time.
I think the ongoing "continue to investigate" messages are fine.
They're obviously dealing with a major incident and trying their best
to keep their customers informed. This IMHO beats silence.

The same thing could and has affected others. Voip.ms has been dealing
with a similar attack for at least a week. We've had excellent service
from Bandwidth for years and I trust that they will be able to get
through this as well as anyone.
It's the nature of the legacy PSTN that redundant providers or fast
failover for inbound calling isn't (yet) a thing.
