Welcome to Second Life Answers, Tenoris
From the information you have given in your original post, it looks like the region/sim that you were on was taken offline. If you log in to a different region - Hissel, Furball, Quarrel are all good sims to log into - open up the world map and see if the region is showing as 'offline'.
Generally, a region comes back up within half an hour, but if it has not done so after an hour, you can click on "help" above and submit a support ticket to tell them a region is offline.

A change is as good as a rest.
