This weekend we’ve moved all of our Sun machines over to our new data center provider, NXS. We’ve moved from Redbus Interhouse to the brand new DCG, which is quite an improvement. I’m glad TransIP has made the decision not to stay at Redbus. Not that Redbus was bad, but DCG is just a bit more modern and secure. It can also handle a lot more servers than Redbus. There have also been some major problems at Redbus lately concerning their flaky power supply. We’ve exploited the downtime to update the servers to the latest Linux kernel. We hope to get the same level of stability from this kernel as the 2.6.18-cks1 we’ve used before.

I’m sure you guys want some specs and pictures of our new home, so here they are. Geek pr0n, if you wish.
