My Network of Servers

I used to advertise my network of servers here to persuade people to pay for hosting.  I still maintain a number but not for commercial reasons anymore but mostly because I have gotten used to having access to them.

These are located in the UK, Germany and the US, with most of the traffic going to one in Germany called Echo and a backup one in New York called Queeg.  I also used to have Shodan (a cobalt Raq 4i) and Xerxes in Texas.  I use 1and1 for hosting in Europe and JVDS for hosting in the united states.

I also use them as a networking testbed; site-to-site VPN's run between distant systems, RIP and IGMP keep the whole thing routing and the entire setup is like a giant real-world Cisco lab only with higher uptime.  There is also a full deployment of IPv6 in place both in my home and on all but one of the servers located in datacentres.

Latest Changes

Please use queeg.nullify.net and echo.nullify.net as nameservers, Xname will provide more backup servers for free if needed. Xerxes.nullify.net is now on a new IP after a relocation from the states.

• Echo.nullify.net (Primary DNS - with IP 87.106.1.170 or 2001:470:1f0b:1154::1 ) is a new server in Germany.  Runs Windows Server 2003 x64.
• Xerxes.nullify.net is now also in Germany on a different IP, this has resulted in it not having glue for the moment.  It is no longer the original xerxes which I had for six years (my first windows dedicated server hosted at a datacenter, prior to that I had used Linux).  The new Xerxes should have the exact same content on for hosted users.  It runs Windows Server 2003.
• Queeg.nullify.net (Backup DNS - with IP 208.116.23.34 ) is still in the United States in New York.  It runs Debian Linux.
• Vex.nullify.net (Secondary IPv6 DNS - 2001:470:91b8:1::2 ) is still in the UK. Windows Server 2008, haven't gotten around to upgrading it to R2 yet.
• Alpha.nullify.net is also in Germany.  Windows Server 2008 R2.
• The routers used are now five port gigabit RB450G hardware firewall/routers running RouterOS from Mikrotik (they are basically small Linux boxes with flash memory and hardware ASICS for routing/switching).  These were a much needed upgrade on Cisco PIX501's which were limited to about 30Mbps of traffic.

Backup DNS for my domains is provided by XName and Twisted4Life, both of which I am very grateful for.

I use SQL Server replication to provide complete redundancy which takes the pressure off if anything does go wrong!  There's a maximum of about a minutes delay before the replicas are in sync and you can update from any location which is very helpful.

The X509 certificate authority used to sign all SSL certificates and IPSEC connections in use on this network is here for you to install as a trusted root if you need to use encrypted services.

Bandwidth

Here's a speed test from one of my servers - note that I have at least a download speed of 85Mbps from this server (fastest I've seen so far though) so the server I was using to actually test the speed can't necessarily keep up - the 'upload' speed is the speed that files hosted on it can be sent to users:-
