Recent Messenger outages
UPDATE (2016-02-12): After more investigation, it seems the DNS reported in some regions (especially in Europe) will connect you to servers that are no longer operating. Reviver has been updated to fix this issue. If you are having this problem, please revive Messenger again using Messenger Reviver 2.4.7.
In the last 24-36 hours, a handful of users have been reporting infrequent outages resulting in error code 80072efd (can’t connect to the server). Waiting a few minutes and just trying again usually will remedy the problem.
Four days ago it was reported on the forum that all the bn1 category servers had disappeared, but the actual connectivity problems with Messenger were not reported until several days later.
So far I have not seen the issue on any of my accounts and therefore have not yet been able to properly investigate the situation. However, at the moment my best guess is that the servers are being reorganized in some way and when you get the error message, you’ve been redirected to a server that is no longer operating. At the end of 2014, the same problem occurred when some of the servers started to phase out direct MSNP and HTTP access. However, I think this might a bit of a different situation.
Although it may or may not be related, during the same time period I have also seen some disconnections with Skype causing it to sign out completely, which usually mean the server has signed me out automatically. These sign outs might indicate that Skype’s infrastructure is also being changed too.
Unfortunately the inner-workings of the Messenger servers have never been completely fully known, so we’ll have to continue monitoring to see what happens.
