jammr will be offline on April 22nd 2019. The maintenance window is scheduled for 7:00-10:00 UTC.
After around 6 years in service, jammr is due for a server infrastructure update. This is a large change but it has been in planning for some time and will hopefully proceed smoothly without long disruptions.
The blog will be taken offline after many years without new posts. The rest of jammr will continue without user-visible changes. All recorded jams will be preserved.
