[Starlingx-discuss] Cengn Mirror server in down?!

Update

All known firewall issues have been fixed.

Jenkins is now up and running on the build server once again. Our first 
manually triggered build attempt of the compiler layer is now running

Of the original ~13000 corrupted rpms, we now have ...

~9250 have been restored, including all rpms that are knowm inputs to 
supported builds

~3100 damaged rpms from the 2.0.0 release will not restored.  TSC and 
community meetings agreed that 2.0.0, being 2 releases out of date, is 
no longer supported.

~650 Have yet to be restored from Upstream.  The jenkins job that pulls 
from upstream sources continues to run.

I would like to have successful CENGN builds of all layers before you 
all hammer the new server with your pent-up download_mirror.sh 
requests.  Please wait a little longer.  We should be back in business 
sometime tomorrow.
