Folks, I strongly, strongly suggest if you use Cloud/VPS providers to look into something like Cassandra, Galera, Mongo, etc. that can do WAN replication and using 3 DCs. Yes it costs money but things like this are avoidable. Every single Datacenter on the planet has downtime and/or performance issues from time to time. Hell, one of the places I have a dedi at had its network performance drop by 50% for about 15 minutes while they did emergency maintenance. Things like this are going to happen as long as you depend on one provider.
