Whenever one of our servers goes down (be it community.openhab.org or myopenhab.org), people start asking on Twitter and other channels if it is just down for them or for all.
To more quickly answer such questions, we have now set up a status page where you can easily check the availability at any time yourself: http://status.openhab.org/
This is how it looks like:
You will find information and statistics about downtimes on that page and we will also announce scheduled maintenance on it. Also be sure that we are notified automatically about any incident and we are doing our best to bring the servers back up again in such situations asap - no need to ping us.
We saw a few downtimes of the forum in the past days, for which we apologize. It seems that our server is simply at its limit with the increasing traffic of the past weeks. The board of the openHAB Foundation just decided to upgrade the hardware tomorrow morning, which will hopefully bring it back to full stability.
