Good support is not exclusive to Linode (_especially_ at that price range). For equally good support at cheaper prices look at BuyVM (NY/CA), Prometeus (Italy), Ramnode.com (Atlanta, if you need SSD/SSD-cached) and SecureDragon (FL). And thats just the ones I have used for my personal use.
I've been using BuyVM for about a year now, and I've had several instances of downtime, including one for half a day, and one due to hardware failure where I lost my data. Also, their support wasn't all that responsive when the server was down.
I'm considering switching to DigitalOcean just for the backups. Are these included in the cost?
