Question / Help Dropping frames out of nowhere

Hello,

I've been using OBS for quite some time now (I think 5-6 months now) and I've never had any problem streaming with it. But today, I suddenly started dropping 40-60% of my frames with the same settings I've been using for weeks...

Now the strange part is that not only my internet is perfectly fine today, but xsplit doesn't let me drop any frames with the same resolution / frame rate. I know the 2 are different programs, but surly this must mean that there's something wrong with my OBS.

Here's a log from today.

I've tried changing the resolution from 1080p to 480p and also tried changing the bit rate on 2k, 3,5k and 4k.
My internet speed: http://www.speedtest.net/my-result/2996235773
I hope someone will be able to help me out here. If I forgot to post any info, let me know.

Try again, Twitch was having some ingest servers that were supposedly fixed within the last hour or so.

Also, dropped frames = network or remote server issue. Lagged/delayed frames = local issue.
Might be that OBS and XSplit are sending to different ingest servers, or that XSplit may be set up with a lower quality stream.

Additionally, Speedtest is worthless for livestreamers. It tests overall throughput, not constant throughput. Run a 6MB test at http://testmy.net/upload instead, to a server close to the one you'll be using as a livestream ingest... it'll give you a MUCH more accurate picture of what you have for constant throughput.

Pretty sure in this case its the twitch fuck up this weekend. Lots of tweets about it and i have the exact same issue starting today, that is on eu servers only - us servers are perfectly fine.
