Syris Technologies promises to have your website/server up 99.9% of the month. This excludes all scheduled maintance, reboots, self inflicted downtime, acts of God, backbone issues, DDoS, and hardware failures. Your account will be credited 100GB bandwidth for every hour your website/server is down.
Maybe you can get 1.9TB of bandwidth added to your account?
So basically, most things that actually will cause downtime, they don't offer credit for? Not sure why they have an uptime guarantee...
Syristech is very unreliable, that's six month experience of mine. My primary site is virtually down for nearly a month. (It can be accessed, but it's not functioning.) No serious support or effort has been made. I'm moving out.
I used to plan to write a 10-month review of syristech. But it seems I can't stay there for 10 months. I planned to write the review these days. But I'm just too busy to do that. I'll strive to write one soon.
