sky 'broadband' was in a house i moved in to in ascot. the speed wasnt that impressive to start with ~1.9mbps during the day. however after a few evenings of watching iplayer we came in to the sky useage radar and suddenly one day our peak time speed all evening until after midnight was throttled to between 0-0.1mbps. webpages take minutes to load, often timing out and of course anything else more intensive, ie. youtube is completely unuseable.

we know this is sky throttling as speed test sites show the upload speed as normal (~300kbps) but when uploading bittorrents the speed is limited to a steady 2kbps which is virtually nothing, so sky is blocking bittorrent protocol.
many others using sky also complain about this throttling.

not contacted sky about this as with all theses big isp's theyll just give you the run around and will solve nothing. best not to sign up in the first place.
if you use iplayer, tv streaming, youtube or upload anything be prepared to have throttling imposed and near unusable internet all evening.
