A sampling of Down Detector comments on https://downdetector.com/status/aws-amazon-web-services/ (which is also showing a spike right now, with no indication of an actual AWS outage I'm aware of):

> Was the internet and #AWS recently hacked? Seems like a lot of softwares are not working properly

> That’s so odd. Wi-Fi is out for me too. AWS outage?

> Another problem which definitely doesn’t make sense why server itself gone wild and not responsive to ssh. We will keep investigating this but it can be aws virtualization issues but interesting.

Slack has to do a little more due dilligence than "wifi's down, must be AWS" for their status page.
