Help Please!?

[[MasterBuilder] Mr_Boss_Man]

I was on the server when all of a sudden it stops, I checked the website and it was down also. A couple of minutes after they both went back online and I joined, but something happened.. When I joined back I was at the new player spawn point and it said "Welcome Mr_Boss_Man to the server" my inventory stuff was all there before the "crash" but when I joined back it was all gone, I checked to see if my tardis was still at my /home location and it was, Think I died before the crash? No, I was in my Tardis before the crash so I didn't die, I don't know what happened, please help?

Update:
Tieko, Me, and two others were on during the crash, so far Me and Tieko joined back and this happened to both of us. The others who weren't on during the crash aren't experiencing this..

Update:
I went to check page 2 of the logs, where before the crash would be logged (I think) and this happens.
