Hello!
It looks like it has some faulty hardware: http://nagios.toolserver.org/cgi-bin/status.cgi?host=amaranth
Yes, the order for replacement got lost in the WMDE office, but they work on it now.
Well no - WMDE *did* inform WMF about this issue several times last year. It's hard for me to follow-up why the replacement didn't happen then and to me, it is more important to make it happen now.
(And when I took over the coordination I wasn't aware that this still needs a follow-up because I thought Tampa was history which is obviously wrong.)
Best,
