The community lab will be undergoing a maintenance period starting on Thursday, February 25th. This is to deploy a new architecture for running test cases that will better support future additions to the lab's testing. This change in architecture may produce instability in the test results provided by the lab, and as such test results should not be considered final until an end to the instability is declared. Failing tests which happen overnight (Eastern Standard Time) will be addressed on Friday morning and will be re-run if they are the result of system instability. Compile, unit and ABI testing will not be affected, although it will be briefly (no more than a few hours) delayed.
