Tune HTTP availability alerts
Closed, ResolvedPublic


The current HTTP availability alerts work and are timely, however sometimes too sensitive and result in false/spammy alerts for e.g. spikes.

Since global availability is fixed in T234567: global HTTP (un)availability number, as reported in Frontend Traffic dashboard, is bogus I'm suggesting we ditch the per-site availability and use global availability instead, if the signal-to-noise ratio proves good then we should turn the alert paging.
