No Explanations yet

They still have no explanation for the outage? Single point failure?

So tell me again why landlines are better?

OK, I know that U-verse voice is more of a VoIP service than a landline, but that's the direction that the telcos want to move in. So, when that happens, won't that negate any advantages of a landline in terms of reliability?

What I'm curious about is what could cause such a widespread outage. If it's a failure in a single piece of equipment, then it seems that AT&T's infrastructure isn't very robust. Not very comforting for something as important as telecommunications.

NSA cable switchover is causing some problems. Hold tight-- your phone, internet, and wireless communications will be 100% monitored by the NSA again very soon.

possible?

Hmm, is it possible that this could be due to massive NAT failure?
I recall reading about some ISP's wanting to NAT out tons of IPv4 addresses since they are so 'rare' anymore... could it be that they were attempting to implement something like this, and it all fell apart?

Sorry to hear about all the fail. Taking it to a recent FB post is probably one of the only ways to reach out and touch them, being such a massive and impossible to penetrate tangled web.

from reading the forum posts, it sounds like hardware/power failure at a major facility.

Reliability is something that comes in time, newer technologies have growing pains. Remember when Verizon had LTE outages which are now a thing of the past.

And U-verse hasn't had a lot of widespread outages, this is the first I've heard of.

More reliability comes with time. POTS can have downtime too, but they are normally more localized.

Re: possible?

I'm going to venture a guess that AT&T has no shortage of IPv4 addresses.

Everyone should pay their bill a few days late when this happens.

From what I read in the AT&T forum on the outage, it appears to be a problem with the DHCP servers that hand out IP addresses. They may have been doing a software upgrade on those servers and the software update bombed out.

My bet.. DHCP servers crashed..

And forgot all the existing IP address lease assignments..

When it comes back up.. it starts handing out already leased(still in use) IP addresses.. to newly rebooted boxes.. I.E. A real mess.

People who left their boxes plugged in/on.. stayed on.. sort of, until a the freshly restarted u-verse box get's a dup'd DHCP IP assignment. Then the games begin.

This type of mayhem could continue on for several days. (depending on DHCP lease interval).

The REAL reason for the crash

Is that Uverse is run by At&t.

Info

We were told there are 32 VHOs are affected by the outage and the DHCP server in TX. No ETR or what cause the outage.

Re: My bet.. DHCP servers crashed..

yes, it is... especially when a network is too large to support wholesale network wide broadcasts.. (I.E. It's some sort of customized hybrid network)..

Perhaps not, but they are nonetheless conserving their use by using NAT:

The above traceroute example is on an AT&T Mobility 3G connection, but they are doing the same thing to U-verse in many areas (and the plan is to make NAT universal for all customers who do not pay for static IPv4 public addresses).

Re: My bet.. DHCP servers crashed..

If you can hand out network wide IP addresses you have enough communication to ensure they do not get used twice. Otherwise this problem would have always existed.

uverse

Glad it wasnt the midwest i just had someone switch from flaky cable and told them uverse is much more reliable lol. Ive seen those 172...... addresses here and there at clients they seem like they are internal to att however when accessing them via other providers they still have external access.

they are very quiet on their FB page about this but if you post something related but off topic they are quick to remove it.

All find and dandy, but what about the Mossad, MSS and KGB? Shouldn't we let the various interested parties install their stuff at the same time? Israel, China and Russia should be spliced in to assure fewer interruptions after this NSA upgrade.

Eggs in one basket

Sounds like the case of the 'ole Eggs in One Basket deal and someone decided to step on the basket rather than spill an egg. I've always wondered why AT&T, Verizon and the like seem to have massive regional outages that take ages to be resolved. In the case of Verizon, it seems once a year a key router in the Northeast takes a dump and breaks about 90% of Internet access that often takes nearly a day to get fixed. I don't know if they're overdue for an outage but Verizon hasn't had their routing fail since last summer.

Granted, even redundancy is capable of breaking as seen with Amazon's hosting service many times but I'm surprised there are not some additional safeguards built in to stop huge outages like this.

The lack of communication is not very assuring though. Sometimes giving customers a technical reason for why something is down is helpful.

Uverse down of course

Uverse is down due to major problems with cicso server equipment and it is just about all south east and west states. Not eta and it might be a long long time since it started yesterday better off going back to prev provider

Canceled U-Verse

Due to the service outage. Just canceled my U-Verse and switched to WOW, scheduled for install tomorrow. AT&T gave me a refund for last month with few questions asked.
