Woke up, turned on my computer - tried to boot up my client. Windows tells me the .exe the shortcut points to no longer exists. I check inside the folder - nothing. I go to my downloads folder, try to run the .exe I installed it from - Suddenly this no longer exists, soon after it dissapears from view in my downloads folder. I try to download it again, when I try to open the containing folder to run it nothing happens - this works for every other file I downloaded. I go back to the download page and get a 404. Every other link on the site still works.

But it gets worse - I downloaded a different client, connected to the mud. Typed my character name. 'Illegal name'. Created a new character to test. That worked.

Edit: tried a 3rd client, seems my character now exists again. False alarm. Still, pretty freaked out.
