Network issues in LLVM Lab

Hello everyone,

Many of you may noticed yesterday issues with the production LLVM buildbot, and yesterday and today issues with the staging LLVM buildbot. The problems were because of problems with the outside connection.

All the problems have been resolved. The production buildbot woks normally as of yesterday. The staging buildbot works normally as of today.

Please let me know if you still see any issues.

Thank you for the patience.
