From our web host or server or whatever the correct term is:
We wanted to send a final reminder concerning the migration of your server to our Irvine data center on 9/24/2012 at 5pm PST. We estimate that the migration will be approximately 4 hours or less of server downtime.
We apologize for any inconvenience this may cause.
From our site administrators:
Please be aware that the FOTR website and forum may be down during the period mentioned.
I believe 5 pm PST on 24/09/12 is 0000 on 25/09/12 (or midnight 24/09/12) GMT/UTC.
