AWS use1 reachability 16:11-17:36 UTC 15 Dec

Hi Folks,

Struggling to get any insight on this so hoping somebody else saw something. We lost about 15% of our traffic into our AWS use1 BYOIP ranges on Friday 15th Dec between 16:11 and 17:36 UTC. Customers reported being totally unable to reach us during the window. Unfortunately I didn’t get a trace to an affected customer nor did any of our monitoring tools pick this up.

Did anybody see anything at the time and, if so, do you have any insights into what happened?
