I have a 2Mb ADSL and a month ago everything was ok.

Now when I try to download any files that are in sites not hosted in my provider the speed goes at 60Kbps maximun.

In case I download files that are hosted in sites of my provide the speed is 200Kbps.

Friends of mine that have the same service can download the same files at same time three times faster than me.

Can the provider block my speed in that way?

If so , how?

Thanks for any help.
