I've put Project BURP on hold. It’s difficult to download the XML files at the moment, possibly due to bandwidth limitations on BURP’s end. This causes update errors for BOINCstats (failed downloads is not something PHP really likes).
Since the first day the project is supported by BOINCstats there hasn’t been any activity on the project. No new users/teams/countries/host and no credit issued. Therefore it isn’t a really big issue.
Current credit from BURP will still be added to BOINC combined accounts. I’ll monitor the project, and when it becomes more stable, I’ll put it back in the update-cycle. Until then I’ll occasionally update the project manually.

Update: I now check the integrity of the XML files before parsing them. BURP is back in the normal update cycle.
