It is related for some since Slack is in us-east-1

I'm not sure these are related (I'm seeing zero packet loss to Slack from Chicago on Cogent) but Slack's definitely broken. Seemed to have been a cascading failure, a colleague of mine complained over IRC he got booted from his, then I got booted from one Slack team, then another.

Slack, which is hosted with Amazon is currently down.

Looks like they solved it by routing around layer42 and go via cogent.  That in itself is a bad idea :/

Yes. 70%+ packet loss from 7065 to all Amazon services as far as I can tell. This was experienced via both layer42 and XO, but Amazon appears to have resolved their issues at this time.
