2015 forward: eQSL.cc is now located in several data centers

Rather than try to describe it to you, let us point you to our provider and the IBM Cloud Data Center page for a better description of our world-class connectivity, power, and operations center support. Our servers are currently located in Dallas data centers, but IBM has facilities around the world, giving us the ability to expand into Europe and Asia as we continue to grow rapidly.

Facility where eQSL.cc was located 2004-2010

A small peek into the 30,000 square foot data center where eQSL.cc is located. Power is supplied by 2 separate grids and Internet access is provided by 8 separate companies!
A row of cabinets sits on a raised floor. Underneath are all network cables as well as redundant power connections.
The network operations center (NOC) on the right is manned 24 hours a day, 7 days a week, to handle any outages, denial-of-service attacks, or other problems, and to perform daily tape backups.
1.5 Megawatt backup generator in case of a failure of BOTH power grids
An additional 1 Megawatt backup generator adds to the capacity of the generator above!
A huge Uninterruptable Power Supply (UPS) will power the entire data center for 80 minutes from batteries while the generators are cranking up
With 8 separate connections to the Internet, eQSL.cc will have a 100% uptime guarantee for Internet access

Old Server (retired January 2008)

In January 2008 we replaced the server below with 2 new servers,
one of them with 1 terabyte of disk space used as a database server,
and the other acting as web server, application server, and mail server.

The Dell PowerEdge 2600 server has won several awards for speed and performance
Dual 2.8GHz Xeon processors share the duties, making everything run faster
Three 73GB SCSI hard drives turning at 10,000 RPM in RAID 5 configuration provide maximum speed and fault-tolerance
Dual power supplies fed from independent power grids ensure that if one power supply fails, the server will continue running

Why no pictures of the new 2008 server?

Our new configuration is 2 separate servers.
The new room in the datacenter housing these 2 servers has such high security,
we are not allowed to show photos of it. Sorry!
