I've scheduled a 3-hour window for the process, although noticeable service interruptions should be shorter. Here's what to expect: - Tools services and existing Labs uses should be unaffected apart from brief ( < 1 minute) interruptions in network service. - Continuous Integration tests (Jenkins, Zuul, etc.) will be disabled for most of the upgrade window. - Creation/Deletion of new instances will be disabled for most of the window. - Wikitech and Horizon may error out occasionally and/or display inconsistent information. Users may need to refresh their web logins after the upgrade. Apart from fixing a few seldom-seen bugs, this upgrade shouldn't result in noticeable changes for Labs users. It will lay the groundwork for an upcoming Horizon upgrade, but that will be announced in a future email. -Andrew _______________________________________________ RelEng mailing list RelEng(a)lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/releng
