Feeds not loading and not updating

Hi all,

So I have a 2-3 feeds added, only one of them seems to up date even though the others also should, they never appear.

Now when I go to other websites to obtain new news feeds, the feeds simply don't load as a web page, they just hang. Safari doesn't recognise the page as being a feed (presumably because its not loading.) So it can't be added.

Is this a common bug with 9.0.3 on Yosemite?
