http://www.mybroadbandspeed.co.uk/ sick again

[#1]

It is giving incorrect speed tests again, at around 80-90% of the download test it either slows to a crawl or speeds up
tested with Opera 11.60 and IE 9

OK here 

[#3]

Working perfectly for me using Firefox.
If anything my speed test was better than usual for this time of day.

[#4]

Working fine here, too...

Hi Gus, is your flash plugin up to date? That might have something to do with it, if it's still happening.

Yes flash is up to date, I was checking the results against TBB's tester and BT's both report the normal speeds, but mybroadbandspeed at times doesn't.
