I am on Telecom BB which I have always been very happy with in terms of speed, but about four months ago I started noticing that pages were considerably slower to load. Often pages don't load at all and give Server Not Found message, then reloading brings up the page. Often pages load unformatted in times new roman with text all justified left and no layout (possibly without CCS?)

If I go to Speedtest, it itself is slow to load, but when I finally run a test it shows a healthy 8mb download speed.

I do have UnblockUs DNS but when I remove all traces of it the problem still persits.

I would normally assume that for whatever reason - new subscribers or heavier usage by neighbours sharing my box - that this is an ISP issue. However, does the fact that I get a healthy speed from Speedtest, plus the fact that they load without layout possibly point to some other cause?

Thanks
