Sorry about the little bit of downtime there. I moved DNS hosts as the site seemed to be coming grinding to a hault. Turns out Level3 had pulled BGP routes so all the traffic was being forwarded via Anycast to an upstream DNS server hosted by my home internet company (Bigpond) rather than the server that was behind the Level3 connection (which was offline). I'm on the phone to Level3 now but in the meantime all traffic has been redirected over Hurricane Electrics, please take note that things may become even more unstable whilst I re-establish BGP peering with Level3.
Sorry... -jD
