The site was down last night until today as the site was moved to a new and better server (host was not changed). Sorry for not pre-advising as it was sudden and I did not have advance notification either. The server was changed to new hardware that is more energy efficient (about 50% less now) but more powerful (4 times) at the same time. It was an effort by the host to cut down their power utilization by upgrading all their servers by batches, so I volunteered to go first in a bid to do something for the environment.
I also took the chance to upgrade our WordPress to the latest version that was released on 10 Dec 2008.
Everything should be fine now. If not, please drop a comment or PM or email me.
Edit on 14 Dec 2008: See article from webhost on improving energy efficient servers. See Let’s Save Our Environment Harder.
