The last two days saw the number of push notifications spike. Sometimes 80K Google Play push notifications happened per hour, while the baseline was more around 10-20K. These spikes probably indicate Internet availability. #deltachat is offline-first: you can write messages and attach media, create groups, use #webxdc apps, setup a second device etc. all without any Internet. Once it returns queued messages are sent out and cause push notifications. #OfflineFirst is crucial for resiliency.
