I haven't been able to find much more than general articles about the fire. The biggest concern, after the possible damage to the builing itself, is of course the records held by some of the heralds whose offices are in that wing.

How much water damage may have been caused to the fabric of the building itself, and how much to the records in the offices in that wing? I'll keep watching for further news, and post links here as I can find out more.
And then (in the interest of completeness) there is the following, a parody "news" story about the fire at the CoA:
