Downtime for devel.rtems.org and others.

[Amar Takhar]

Several of our sites will be going down randomly starting this afternoon 
2023-09-16 GMT to 2023-09-18 8AM GMT.

Given the importance of GSoC I hope to have this work done before the weekend.  
The sites that will be down are:

  lists.rtems.org
  docs.rtems.org
  git.rtems.org
  devel.rtems.org

Commits will be unavailable during this time as well those will be enabled last 
with devel.rtems.org getting the highest priority for GSoC this means the other 
services will take longer to come up.


Amar.
