Looking at bgplay data, Hetzner possibly had some outages at the time?
Cogent isn't quick at withdrawing routes and will often blackhole inside
their network, but i can't see a large leak/hijack as happened.

A report that all Cogent traffic got re-routed into Moscow. Looks
innocent but happened right after UA blocked RU websites (e.g.,
VKontakte, Yandex, etc)

Any thoughts ?

Similar happened like 3 weeks ago.  Big collective yawn when I posted
about it.
