--------------------------------+---------------------------
 ==== Scope
 !AsIs: Some of the critical services powering the Tahoe-LAFS project
 (mainly this Trac instance) can become unavailable w/o any active member
 of the community being notified.

 In many occasion, the downtime has to be reported by people on IRC (or
 [https://github.com/tahoe-lafs/infrastructure/issues/46 elsewhere]) before
 someone with the proper access can take action.

 !ToBe: Implement a basic monitoring solution tracking the availability of
 the critical services and allowing relevant people to be notified as soon
 as one of them is detected as unavailable.

 We are proposing to use [https://github.com/upptime/upptime Upptime] to
 achieve this, and the end result can already be seen
 [https://leastauthority.github.io/tahoe-upptime here].

 ==== Value

 - Contributors would be able to see past and ongoing downtime's.
 - Maintainers would be able to be notified to take corrective action
 earlier.
 - Statistics about the availability of the services will be publicly
 available and support future changes.

 ==== Requirements

 - Transfer the existing git repository (already provisioned with Upptime,
 CI and pages) from LeastAuthority to Tahoe-LAFS org. on GH.
 - Reconfigure owner/org name where needed.

 ==== Additional information

 This enhancement is a very nice to have for the execution of the
 MoveOffTrac project, in which it is planned to replace the issue tracking,
 wiki and web landing page solution, and hopefully improve their
 availability.
