If you know your FRC district Director email them. The FRC wants updates every 2 years and if your repeater freq ends in even number the update is to be submitted in odd year and if odd number update in even year.
Normally one can update on the web site, special form for this, but since the site is down cannot do much there as you know.
Here are some contacts for FRC:
Dana, K4LK, Coordinator & Database Manager
District 4 director, Mike Fletcher, NI4M
If you know your district I am sure you can use dir(X)@florida-repeaters.org, but contacting the others should get you to where you need to be.
