100% Tier-1 Gogent
but both were on ChicagoVPS
There weren't too many hosts smacked by this. RamNode was the highest profile provider around here and while it took time, I think they rescued everything.
There were something like 1000+ people who had more than one VPS with CVPS. So, that practice is roughly 10% of their total VPSes deployed.
There are companies who aren't based on SolusVM. There is an ongoing thread about that on here. Backupsy comes to mind and BlueVM and BuyVM (I think).
You can cheaply create failover capability with 3 VPSes (different providers) and Rage4 DNS (free depending on your use). For database security do cron jobbed mysqldumps and scp those off to a remote backup storage like Backupsy. Ditto for source files, rsync them over to Backupsy. Synchronizing the database from the failed over to node is another complex story, but minimal impacted users in that scenario.
