Invalid gamertag?

[Xbox Live Man]

I havn't been able to play online since yesterday & now my card says its invalid, I understand it says tech issues aswell, but no one elses tag in their sig has gone like mine...so what does this mean? I'm banned from XBL? Cause I havn't done anything, I'm still on 100% positive rep...& if I have been banned, what could the reason be???
