Is Youtube playback choppy for anyone else right now?

Since very late last night, I've had problems with Youtube video playback. I've tested it with 2 separate PCs, same results. I can play videos on cracked.com, Cinemassacre and TGWTG just fine, it's only Youtube that's giving me issues. Videos are slow to load and lock up frequently during playback. I tried updating Firefox and Flash player, it didn't fix the problem, and since 2 PCs are giving me this problem I doubt it's a software issue anyway. So is anyone else having the same problems right now with Youtube?

What browser are you using?

Firefox? Does it happen in chrome or internet explorer?

Since other sites work fine, try clearing the cache in your browser. Firefox does lag sometimes, even on powerful pcs. They recently updated firefox though and it is much faster.

Click help-about firefox.

Follow this to do a clean install of Adobe Flash. Adobe Community: How do I do a clean install of Flash Player?

Do it for Firefox too of a clean install of Flash does not solve it. https://support.mozilla.org/en-US/questions/964662

Remember, you will have to reinstall addons and extensions and reinstall Flash too.

I was using Firefox 21 prior. Here's the thing- Youtube was working fine one moment, then a few hours later with NO CHANGES to the PC, Firefox or Flash player, youtube goes choppy. No restarts, no anything. I get the same errors on a separate PC as well so this does not seem like a software issue on one PC. I'd left one of those "idle" flash games running while I was away from the PC for a bit, which I've done multiple times before, so I don't see how that affected anything, nor could it have mattered to the other PC. I am coming up totally clean for malware.

Right now I am using Firefox 29 with the current flash player. Same issue. This only affects Youtube playback. Updating the browser and Flash player didn't fix the issue.

I tried to use Youtube through IE, videos would not play and I don't have any other browsers installed. as of now Youtube playback is still choppy to the point I can't watch most videos, while other sites still work just fine.

I've cleared the cache, no change. Disabled Flash's hardware acceleration, no change.

edit- I just tested videos on Vimeo and Dailymotion, they play just fine. This seems to be a Youtube issue.

edit 2- IE is giving me the same playback error on BOTH PCs.

IE also gave me this about an error on a video page, may be relevant-

Try restarting with addons disabled under the help menu in firefox. See if the issue persists.
You could also see if installing chrome has the same issue, or try updating your graphics driver.

I'm going to assume this was an issue on Youtube's end- videos are playing fine now. I'll watch a few more but videos are loading properly now and I haven't had nay freezes or choppy playback.

Great news, let us know what happens
