I as blogged about earlier I've now changed ISP to Goscomb Technologies. Quite a straight forward migration and although the downspeed isn't much better, it's a lot snappier which implies I was congested on the Demon line. However, my upload speed has doubled, which is good news for this server 😄
There maybe some more downtime in the near future as I may change registrar as I'll be getting native IPv6 later today (yay, no more tunnel!) and my current one (1&1)don't appear to support IPv6 in their domain / dns setup.
