That's been either me setting up the Firewalls and blocking access to the license server. Or John rebooting servers. Teamspeak will run for about an hour without talking to the license server and about 2 hours without a database.
Since the cloud isn't one single server there are multiple parts that can break, and some that some services can live without. Database, Site, and TeamSpeak are our 3 "droplets" currently.
That being said I've only seen the server crash while Pika is afk, and that never happens... so...
