Development Laboratory and Computer Room
Although much of our work is directly upon client machines, usually via VPN and VNC connections, we have an extensive development laboratory and computer room complex.
We have duplicated connections to the web, serviced by separate firewalls (each with an additional cold backup), augmented by a bank of inbound and outbound modems across multiple phone lines to ensure accessability in the event of problems with the local external web infrastructure. Our web servers are duplicated, with automatic fallback.
All other essential servers are triplicated, with automatic fallback and graceful degradation, while all equipment is supported by a bank of UPS devices.
We run numerous physical and virtual Linux hosts, mostly running Debian, but almost all other dialects of Linux and available on (usually quiescent) virtual servers.
The entire complex is built upon a Gigabit backbone, for ultra-fast server synchronisation and backup. In addition to local backup, with all data archived on a minimum of 3 separate physical hosts, we maintain offsite security copies in multiple locations.
