[Astro] [CAPT] Captain being rebooted this lunchtime (~1-2pm Weds) (was: Re: [Particles] Fwd: FW: IMPORTANT REMINDER: Physics building loss of power for urgent maintenance: 09:30 to 13:30, Wednesday 3rd September)

[Phil Parry]

Hi all,

This is in progress, and the servers in Physics are now shut down while 
electrical work takes place.

Since captain seems to be unused at this moment and it's in need of 
updates, I plan to install them and reboot early this afternoon, as soon 
as the power comes back on in Physics.

I hope this is OK - please contact me this morning if this will be a 
problem for you.

I'll email again later today with an update.

Cheers

Phil P
