I downloaded the 6.2 update on 8/23 and started playing around 5pm PDT until midnight with no issues.

I logged into the game on 8/24 around 7pm PDT and noticed small lag making it impossible to play with others. After troubleshooting and testing for packet loss - I saw the recommendation to reset my router. I reset my router around 10pm. The lag disappeared.

I logged into the game today on 8/25 around 5pm PDT and was fine. I logged out at 5:30 and returned at 8pm. The lag was returned. I tried resetting my router and it did not fix it.

I have since followed the instructions here and submitted the necessary information https://na.finalfantasyxiv.com/lodes...a451d5a8daa66f

8pm - 10pm, unsure if any other times as I cannot test it.
