[Systems] [Sugar-devel] git.sugarlabs.org down for unplanned maintenance

If it is necessary it could be moved.
Sugar Network at this point is "in production" and we do have a process 
for deployment (there is testing and devel instance).
Alsroot has had a pretty good track record of keeping git up and 
running. I think it's a shame people are moving to github.
What we should be asking I think is how we can provide better service 
for our users/developers (for example, having more people monitoring 
services and reacting when things crash).
