<div dir="auto">This is congestion between NTT and AT&T, not an NTT internal issue. I've run into this as well and NTT has let me know that AT&T is refusing to upgrade their peering ports in places where there is congestion. I doubt that contacting AT&T will be fruitful in persuading them to change their mind, so my recommendation is to use another carrier to reach AT&T customers.</div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, May 17, 2023, 7:03 PM Scott Wrosch via Outages-discussion <<a href="mailto:outages-discussion@outages.org">outages-discussion@outages.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

<p class="MsoNormal">Hey folks - <br>
<br>
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
<a href="http://ae-1.r20.dllstx14.us.bb.gin.ntt.net" target="_blank" rel="noreferrer">ae-1.r20.dllstx14.us.bb.gin.ntt.net</a> and
<a href="http://ae-2.r24.lsanca07.us.bb.gin.ntt.net" target="_blank" rel="noreferrer">ae-2.r24.lsanca07.us.bb.gin.ntt.net</a>, 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. <u></u><u></u></p>
