Networking equipment graciously provided by:
Like many sites, our servers are hosted in a professional data center with fully redundant upstream providers. We use Cisco routers for gateway connectivity, and Foundry network switches for 100BaseT and GigE ethernet connectivity to each server.
IPv4 space is provided by our very own legacy /24 ARIN network block. IPv6 is provided by Hurricane Electric's Tunnel Broker system.
The bulk of our servers are HP/Compaq Proliant servers with RAID arrays and iLO management running Debian Etch.
Our network partner is Wiztech Internet, who provides co-location space at OpticFusion. Of all the providers we have evaluated and used in the past, OpticFusion by far has gone above and beyond our expectations in terms of price, performance, and support.
