Intent to Decommission: This List (dev-telemetry-alerts@)

[Chris H-C]

Hello,

Summary: I plan to decommission this list (no more emails to/from, wiping
the subscriber list, etc) on or shortly after July 17, 2020. Expiry alert
emails currently sent (by default) to this list will be sent instead to
glean-team@.

This list was originally built and maintained as a place to notify people
about and discuss alerts detected by the Telemetry Regression Detector
system (cerberus). It expanded in scope to also include automated expiry
information, then cerberus was disabled as part of the Data Pipeline GCP
Migration (because it wasn't worth porting given its poor performance on
then-current data collections, and lack of maintainers).

So now the only function of this list appears to be as the "default
addressee" of the probe-scraper-driven expiry alert emails in the event the
expiring probe has no notification_email value set. Well, that, and
receiving low-level spam that escapes the filters.

We don't need a full mailing list for receiving default alerts. This
function can be supported by a mozilla-maintained distribution list (I
propose glean-team@) which I then don't have to moderate and administer.

If you've read this far and noticed that I've encoded a lot of
assumptions into this email, good for you! There might be other uses this
list is currently being put to that are just low-frequency enough that I
haven't noticed, or there might be benefit to using an open-subscription
Mailing List over a moz-only Distribution List as the default addressee for
probe expiry emails. If any of these (or other) assumptions are wrong, or
you have other opinions or ideas about this proposal, please do reply.

Otherwise, in absence of opposition, on July 17 I'll file patches against
probe-scraper to point emails to glean-team@ and find someone (I can't find
the delete button myself) to remove dev-telemetry-alerts@ (preserving the
archive if it isn't too much of a burden).

Thank you for your attention,
