Service disruption guide

Service disruption guide

This page is primarily for the team. It's public so that you can learn from it. For help using, see the user docs.

This guide outlines how we handle communications for service disruptions during East Coast business hours.

Not a guide for:

  • Hours outside of East Coast business hours – out of scope for this document.
  • Security incidents – switch to security incident guide.
  • Major service disruptions (more than 30 minutes of unexpected downtime or significantly reduced service) – switch to contingency plan.

Threshold for “service disruption”

If there is an unexpected user-impacting problem that we believe is a platform problem.


  • We caused end-user-visible errors in customer applications.
  • A platform-owned component such as the dashboard or brokers is giving errors.
  • Two or more teams using have reported the same non-trivial problem, which indicates it isn’t just a problem with a customer application.
  • AWS or another service we depend on is causing problems for our users.
  • Something unexpected went wrong during scheduled maintenance, and it impacts users.

How soon to post to Status Page

As soon as possible. Goal: at most 15 minutes after the first team member notices the problem.

Who is responsible for posting and updating

  • First person on the team who notices a problem is responsible for finding the right people to address it (can include themself), including finding a person with Status Page access to post about it (can include themself).
  • Platform squad person on support rotation should be the first person to begin addressing the technical issue (and the first person for non-platform squad people to ping for help with this). See the platform squad channel topic for the current person.
  • A person should explicitly say “I’m taking care of Status Page for this” and continue being responsible for updates until they explicitly hand off that responsibility.

Drafting and approval

  • If you’re platform squad: Draft and ping for comms help (Bret, Britta), but if they aren’t available within 5 minutes, just post it.
  • If you’re not: Draft and ask platform squad for technical check before posting.

We have some templates and drafting space in this doc.


  • If you’re writing an update to a post about a new related problem, also update the post summary (the subject line) to make it summarize the whole event.

When to close

We close the event when we believe the disruption is no longer affecting customers.

The person with Status Page responsibility is responsible for asking “any objections to closing it?” and closing it if none.

  • It’s helpful but not required to write something that’s informative about the resolution as a closing message.

A postmortem is not necessary to close, and it does not have to happen immediately after closing.

Ensure a postmortem happens

The person who closes the event should then put a card on the component-owning squad’s board in the urgent lane about writing and posting a postmortem.

For non-security-sensitive work, work to resolve root causes does not have to be completely done before we post the postmortem.
