I don't really care if you don't believe me. This isn't the first time this has happened, although the last time the speed was only a 5th of what it was this time. I spoke to my uncle about it (who used to own a computer programming and maintenence company and now programs computer for satelite tv channels) and he said that from time to time, when your ISP isn't busy it puts out ridiculous speeds. My other uncle builds computers for the Ministry of Defence since he retired from the R.E.M.E and he said there could be several reasons for this happening.
