The servers that power our hosted help desk are located in two Amazon's datacenters - "US-East" (North Virginia) and "US-West-1" (California). The building is powered by multiple sources, the electrical service is connected to UPS devices, that deliver the power to the servers. Power is also backed up by multiple diesel generators that back up each other.
The datacenter features a precise cooling and humidity control system, early fire-detection system, multiple Internet connectivity providers (Level-3, Comcast, AT&T, Verizon and others), intrusion-detection and monitoring systems.
We are hosted side-by-side with Reddit, Github, Airbnb, Foursquare, Instagram, Netflix, Pinterest and many others.
Hosted on Amazon is not cheap, but we prefer to pay more to provide higher uptimes. We know that our customers rely on Jitbit to do their business and we cannot afford to have any outages. In fact, we have never had a major downtime in our history. Despite serving thousands of users every day the longest outage we had was about two hours during seven years of our history.
We also offer an optional CDN "cloud hosting" feature, read more about it.
