It appears to have gone down with a serious problem. Having done a fair bit of work in IT, I know the error that is appearing all too well. It's basically saying that the data server is down.
The implications of this are that PBLiveScores may not be up again today, given the fact that it is Sunday. However, depending on where it is hosted there might be some hope yet.
Of the information I have gleaned doing some basic research, I get the impression that the site is hosted in a datacenter in Poland, probably owned by a polish telecoms company, but the set of numbers being revealed by the error message indicates that it is an internal server that has gone down, and quite possibly could be a server not under the control of pblivescores, but sylogic instead.
