Waiting for s.ytimg
*Not sure if this is the right place to post this, in fact, I don't think it is, but I wasn't sure where else it would go.
For the past week or two I've had trouble connecting to certain websites (YouTube mainly, but I've also noticed that it happens with the adobe website and some smaller ones too.) No other computer in the house has trouble with this (they're all PCs, is that relevant? Not sure if this is a mac thing).
The website doesn't load and I'm left with a blank page while my browser's status bar says that it's "Waiting for s.ytimg..." (<-- for YouTube, anyway. For other sites I get stuck waiting on 'google-analytics', 'wwwimages.adobe.com', and some others. But I'm using YouTube as an example because it is causing me the most inconvienience since I use it regularly.)
I've tried googling solutions but haven't really come up with much, other than it's possibly a problem with Flash Player. I've tried blocking 's.ytimg.com' in Flash Player's storage section in System Preferences and it worked, for about half an hour, then the problem was back. I then tried uninstalling Flash Player and reinstalling it. Again, it worked--temporarily. (I also tried clearing cookies and cache before this but made no difference.)
Does anyone have any permantent solutions? It's really starting to drive me insane.
Any help would be appreciated!
