@hiczok I have the same problem, HTML5 HD videos used to load nice and quick. Now nothing loads, the streaming option cuts out after 2s even on low quality... The downloads don't start and if they do they crap out after a while, The really sad thing is that this has started to happen to the podcasts/mp3's aswell... My connetion is 100/10M and no other websites have been acting up.
The site has been fast and responsive in all regards for me for a few months. Besides notifications being broke and the video player being crappily designed (though it streams video fine for me) all is well. Pages load fast and videos play quicky and don't stop so they can buffer.
