I'll update this page
in the future to include this data, but in the interest of time, we have two categories of blockers and two types of SLOs:
- Urgent blockers are blockers that are tied to a release scheduled to ship in a week or less (e.g. a dev blocker for M91 when M91 is currently shipping to canary / dev, a stable blocker for M90 when the M90 stable release date is less than a week away)
- Standard blockers are all blockers that aren't urgent
- Comment SLO: How often the assignee needs to comment on the bug (recurring), measured from time of last comment (or when issue was assigned if no comment present)
- Fix SLO: How long the assignee has to fix the bug, measured from time issue was assigned
For urgent blockers, we want to see comments every business day, and fixes within two business days; for standard blockers, comments every other business day and fixes within five business days. We feel folks should always be able to meet the comment SLO, and folks should usually be able to meet the fix SLO, though we acknowledge the fix SLO is sometimes tough to meet depending on the issue at hand, it's more meant to encourage folks to revert quickly where viable rather than fix-forward more slowly.
I can circle back here when the doc linked above is updated and if / when we have tooling to help query and measure these available for public consumption.
