Problems with HTTP monitors and alert delivery
Incident Report for DataSet
Resolved
Today from roughly 11:30 to 12:10 UTC, some HTTP monitor checks were not performed properly. Some alert notifications may also have been delayed during this time. For a small number of customers, alert notifications were not restored until around 14:30 UTC.

The underlying issue seems to have been a widespread networking problem in AWS us-east-1. We're still investigating to confirm this. Meanwhile, all problems are resolved at the moment so far as we're able to observe.
