Quote from LondonHedger:
Of course if it turns out the problem is indeed at BT's end we're probably screwed. Just imagine trying to explain to someone at a BT call centre that your broadband doesn't work with streaming financial data (but it does with anything else) after 7:05pm and you think it's BT's fault... I am not sure what kind of protocol IB uses to broadcast streaming quotes, I will need to find out if I decide call BT to discuss this with even a remote chance of success.
Don't!!
I'm just wondering if the contention ratio changes at peak times (ie after 7pm when the casual browsing crowd come online)
Maybe BT is confusing financial data for some kind of file sharing and limiting the pace. But it recognises streaming video/audio and doesn't interfere as it knows it will affect the users experience.
