There were actually three attacks on the same day. The first (about
12:00 UTC) affected pretty much just the Eastern USA, and we saw little
beyond some raised RTTs in Europe. The second (about 16:00UTC) took out
all the Dyn POPs in the USA and affected their European POP. The third
(around 18:00UTC) ... was pretty much a non-event. Dyn had mitigated
the attacks pretty effectively by that point.
Cheers,
Matthew
