It appears that Eftel have took the power down again at the colocation facility in Collins Street, but unlike last time it would appear that the server isn’t back up yet. This could be because the outage is still going on (it’s still listed as current on their site as I write even though it was scheduled for just Saturday) or it could be that there’s a problem with the box.
The LUV sysadmin has tried to get permission to go and investigate today (Sunday), but it appears it won’t be possible until Monday.
