After several years of recommending people to Pipex, I would never do so again.
I have found out, after wondering why my Bit Torrents were suddenly downloading so slowly, that Pipex (among some other ISPs) are apparently throttling the range of ports used on file sharing networks, and according to several other forum posts (on various games / file sharing forums), have not even had the courtesy to inform their customer of this. Not all file sharing is illegal, and in my opinion, they have no right implementing this strategy, when broadband services are advertised as being 'unlimited'.
I therefore decided, after long consideration, that I wanted to switch my broadband provider, and found a lot of good reviews for
Namesco, on ISPr. They offer a 2Mb package (10Gb capped) for £19.99 per month, whereas I am now paying Pipex £23.44 per month for a 1Mb package, and Namesco have confirmed by e-mail that file sharing ports are not throttled.
I have just phoned Pipex to request a MAC code, in order to migrate my connection, and was told that I had to pay a £58.75 cancellation fee, because although I have been with them for three years, when the minimum contract term is one year, when I moved house last September, this constitutes a new contract, which I am bound to for 12 months.
I am now in the right frame of mind to take them on legally, but have no concrete proof of the port throttling (apart from tittle tattle on various forums), and would probably not have a leg to stand on as far as the minimum term contract goes either. Suffice to say, I would never, ever, recommend this company again, and will be leaving the day my contract expires, which is unfortunately not for another 6 months, then it will be Pipex...
