Not quite the same thing as the BBC's previous streaming diagnostics page...
Agreed but if one is having issues with streaming from the BBC then that .jpg file can be quite useful for testing using software such as JDs Auto Speed Tester. I ran it last year for several weeks due to a HD streaming problem during weekday "office hours" and it was actually more convenient than frequently accessing the iPlayer diagnostics/speed tester page. The results went to my ISP and the TTB routing issue was resolved
