The LLVM server will be offline this weekend (2/19-2/21). You will not have access to the website, svn, bugzilla, etc during this time. The mailing lists should not be affected.
I can not give an exact time estimate, but starting friday afternoon until Sunday night. I'll try to keep the downtime to a minimum. Once I know more, I will send mail to the list.
Thanks,
Tanya
