2019-08-11: Switched to a new database backendToday, the database servers has been migrated from a master-slave to a multi-master architecture (2 DB nodes + 1 quorum). Everything is working as expected, but maybe some adjustments have to be made in the next days. This shouldn't cause any issues, but who knows.
2019-07-31: XMPP - prosody to ejabberd migrationAs first part of the long planned prosody migration I have finally started with the evaluation and testing of ejabberd. This will take some time, as there are some dismail specific things to take into account. If I do not come across any showstoppers, prosody will be migrated to ejabberd in a few weeks.
2019-07-24: fdns1 - some head scratchingWith the last maintenance two small nasty bugs slipped in, which made some DNS clients to fail sometimes, under some conditions.
It took me quite some time, but everything should work fine again - if not, please let me know.
2019-07-18: fdns1 - Scheduled maintenance on Friday, Jul 19th 6:30-8:30 UTC.Due to maintenance work, the DNS resolver fdns1 will not be available on Friday, 19th between 06:30 and 08:30 UTC

2018-12-06: Prosody 0.11.1
Prosody 0.11.0 has been released on 2018-11-21 and a few days later Prosody 0.11.1
So why haven't I updated yet?
- The upgrade and migration of the mailsystem was and is very time consuming, but it's worth it.
What we have now: load-balanced, georedundent systems which I could swear are also somehow hyperconverged ;)
- I am not an early adopter. The new software release needs testing even if there are no significant changes. The running Prosody version is at a local stable maximum with some known minor issues. The new release don't has any killer feature forcing me to upgrade in a hurry.
- The upgrade will be combined with a new server and a lot of testing and this needs time.
