they'd go after it via a single vendor and have it be so effective. It used to be coordinated attacks against the root servers, but I guess those have been easily mitigated for some time now.
Neither Twitter nor Reddit are down, nor is Paypal. They are inaccessible to some based on where you're coming from (geographically + ISP), but they're still functioning for plenty of people.
The earlier attacks focused on the east coast. At about the same time that it seemed those attacks had been mitigated, the traffic surged a second time and focused in on west coast (and a limited number of European) targets.
They basically waited until the start of business on the west coast to turn it up there.
Spent the whole morning sick in bed and trying to figure out what was going on.
As you mentioned Twitter is down. Reddit is down.
This is pretty wild.

These DNS servers were hit by a terabyte per second! Damn.
