AWS hosted sites like slack unreachable

You didn’t specify anything that would be useful to narrow down the issue (i.e. location, asn, error codes, etc) - We had a somewhat similar issue at DET-IX with routes to us-east-1 and us-east-2 seeing a lot of packet loss, but AWS eventually just de-peered the exchange entirely since it was an issue with their equipment.
