Osmocom scheduled outage on *2020-07-19 9am CEST*

19 Jul '20

There is an urgent need to migrate our most important public infrastructure to a new server, and I will be doing that on *Sunday, July 19 2020*, starting about 9am CEST. The migration involves redmine (main osmocom.org website), jenkins, gerrit, git, and cgit. In theory, the migration should be quick. I would expect (significantly) less than one hour of downtime. However, we all know Murphys law. Services not affected are mail (including mailman lists), ftp, dns. So in case of doubt, we can still use mailing lists to communicate. In case anyone urgently needs osmocom source code on Sunday morning during the downtime: There are public mirrors available on github.
