[Scott Wrosch]

I’ve definitely been seeing issues in game, coming from the Detroit area.

This is a pretty vague problem report. Are the source/dest on-net with NTT or are one or both sides behind another carrier? What time(s) is this an issue - all the time or just certain times of day?

Hey folks -

For the past 3 days or so, there seems to be some high latency between the Dallas and LA exchanges of NTT. Specifically, it seems to be the hop between ae-1.r20.dllstx14.us.bb.gin.ntt.net<http://ae-1.r20.dllstx14.us.bb.gin.ntt.net> and ae-2.r24.lsanca07.us.bb.gin.ntt.net<http://ae-2.r24.lsanca07.us.bb.gin.ntt.net>, where there's observed latency increases of about 60-70 ms. This was raised to my attention through the Final Fantasy XIV community, where East Coast and Central US players are experiencing high jitter. Curious if this is affecting anyone else's traffic.
