Hi Marco,

I can't ping svtsystem1 either, so maybe it didn't come back online?

>From what I remember that computer isn't located in EEL/124, but rather EEL/231.

It should be located against the wall  next to a small switch in the corner between where I normally sit and Marc, you can have security unlock the door since it is probably locked.

Unfortunately, since it's a clon based machine I don't have any admin permissions on it. Nathan or Wesley do if it still doesn't come online cleanly.
