Horrible evening connectivity and timeouts in the Austin/Dallas areas now on its 11th day!

Spinning off a new thread instead of mixing into that (laughable) gaming latency one.

I went back through my logs, this issue has actually been happening every evening since January 9th! Tonight it started early at 6:15 PM CST, likely due to being a weekend.

As noted previously, this is not just a ping/traceroute issue, this is connectivity failure and timeouts with many sites, including Google, YouTube, and any sites that import Google content (i.e. everyone).

Here's the latest, 565 ms through to 8.8.8.8:

$ traceroute -n -w 1 8.8.8.8

I know you’re right, but I would like to think that customer support would be able to check some internal issue tracker and confirm an issue is being worked.  I’ll sit down and shut up now.

As @blocknonip has already stated.. right on queue again this evening. 

@browndk26 I can almost guarantee this is fairly widespread (at least in our area and perhaps not affecting business customers), it is just not very easy for the average layman to understand and identify the issue. I've got a high level network engineer just down the road experiencing the exact same issue who is also on ATT fiber (he's a CCIE). There are numerous accounts here in the threads as well as reddit and dslreports.com forums. I'd wager this is quite widespread.

We don't really need high level engineers here to assist, just be nice for someone to pass it along through the appropriate channels and note here that it has been escalated. I'm sure that's probably asking too much from a multi-billion $$ corporation /shrug.

How widespread would you like? I spoke with a couple colleagues using AT&T fiber in my city (not on my street) with the exact same experience over the past week. One was quite perturbed that he hasn't been able to watch YouTube in the evening for multiple days without the stream constantly stopping and restarting every minute. I think we've had people chiming in from both the Austin and Dallas metro areas...

Latest results are over 1000ms to www.google.com and github.com and counting!

@blocknonip Looks like we can add twitter to that list as well.. Saw a peak of over 1400ms.

Looks like the 32.0.0.0/9 is the start of it (334ms avg), but then the handoff to Level3 in Dallas is really bad too.

I'm in Austin, TX, and experiencing this issue. I've shared some data below, but please let me know if there is anything else that would be helpful.

Support here by Att  as was mentioned is intended to help people resolve issues that can be done by end users.  The assumption some higher authority is reading here and will accept your trouble report is just not so. 

Having said that, the more detailed and factual information provided with good problem determination methods might be actionable.  And even when a smoking gun is produced, it can take several months to move the needle.

@blocknonip . as @gr8sho  says, the forums are primarily designed to offer "self-help".  When something like this happens, the ACEs try to recognize it and bring it to the attention of AT&T.  This has occurred here.  Additional data, especially from additional customers in this same geographic region, help to demonstrate that it affects multiple customers and try to keep them from continuing to wait to do checks on each individuals home connection.

Mentioning ATThelp doesn't actually function, and they don't really have much to offer directly anyway at this point.
