Hello,
I have been having really bad ping during the peak time (EU) since Orsinium DLC (usually over 200). It used to be 70-80ms at max during peak times but nowadays I get such ping only during mornings or early afternoon. After 6pm GMT+1 my ping is really bad and it affects my gameplay a lot. I usually play only during evenings so it's really frustrating. I tried to ping to eso site and I have around 130-140ms. My connection is fine, I run some speedtests and my speed and ping is fine so there is definitely some issue with ESO which wasn't present before Orsinium DLC. I was talking with my friend which lives in the same city as me and his ping is fine, around 100ms in the game during peak times so I don't really know where is the problem but any help is appreciated. I have not changed anything in last month with my computer or connection.
