[LLVMdev] Potential Downtime of LLVM Server on Jan. 6

[John Criswell]

Dear All,

Just a reminder that some work on our heating/cooling system will be 
done tomorrow between 8 am - noon Central time.  If server room 
temperatures get too high, the IT staff will start shutting machines down.

Since the LLVM server may need to be shut down on short notice, I can't 
guarantee that we can give you advance warning of it going offline.  I 
strongly urge everyone to avoid using SVN during 8-12 Central time tomorrow.

Thanks.
