For the low priority that 'infrastructure' is given, very likely.

s@h had to go to the trouble of installing their own data pipe out
to the outside world, helped by a very generous sponsor. I very
much doubt they've got the high profile or funding required to
also get their own dedicated redundant power supply.

Ok, let's cool off a bit and clear up a thing or two.

First, the power issues are affecting the entire Space
Science Lab, not just the S@h project. It's not a matter
of an extention cord or an extra outlet in the S@h lab.

Second, this isn't just a matter of a couple of 200VA
UPSs from Circuit City or Best Buy to fix. For an idea
of what equipment is involved in just supporting S@h
Classic, see:

and scroll down to the bottom; check out the third from
last picture or last picture.

A 200VA UPS might support one or two of the network
switches in one of those racks; no way would it hold
up one of the E450s or even one brick of the hard drive
array.

They already have the best power they can get from the
facilities people in this server closet. However, that
entire closet won't hold a large enough UPS to keep
those racks up through a 3 hour outage.

I have no idea what equpiment has been added in support
of SETI+BOINC, but I'd guess it is another two racks
worth of servers and storage arrays. Those, of course,
require additional power/backup/cooling.

Being a network admin myself, I have a lot of sympathy
for the position they're in; I've had to deal with irate
users when trying to recover from a disaster caused by
events beyond my control. I have no doubt that they have
facilities people working on the problem, but all they
can do until it's fixed is what they're doing now.
