Fire At AT&T Facility Causes Outage For Over a Million U-Verse Fiber Customers In Texas (wfaa.com)
New submitter JustChapman writes: Local Dallas/Fort Worth WFAA is reporting a major outage of AT&T U-Verse fiber internet, due to a lightening strike at a switching facility in Richardson, TX. Apparently the strike took out primary and secondary power systems, setting fire to the building. One commenter states a representative allegedly said that 1.5 million customers are currently without service.
U-Verse met its H-Death.
Thank the maker I don't have AT&T as my ISP, but it remains to be seen if I have internet at home.
However, given AT&T's past transgressions, Somehow it makes sense that the Maker is mad with ATT and struck them with lighting.

Lightening is where you lighten something up that's dark such as a photo in digital photo editing software.
Lightning is the high-energy burst that almost rivals a nuclear bomb, causes audio compression (i.e. a thing called "thunder"), and can start building fires even if the building is properly grounded.
Hopefully, this has been enlightening for JustChapman. Get a dictionary!
Lightening strikes usually result in liftoff and sometimes an abrupt crash, equally devastating, and fire is a common feature...
deleting the extra space after periods so i can stay relevant, yeah.
This sounds eerily like the 1988 fire at the switching center in Hinsdale, IL. Hopefully they didn't ignore alarms as happened then.
Oh, no! You have walked into the slavering fangs of a lurking grue!
You really have to hand it to these people. They put the primary and secondary power systems together in the same room.
This is cluelessness on a grand scale.
I don't read your sig. Why are you reading mine?
I've got AT&T fiber down in the Houston area and it works just fine currently. Ditto with someone I know in the Austin area.
This is why you need two sources of internet (wireline and wireless), and why when AT&T says LTE is 10mbit 3G good enough for the rural bumpkins, smack them.
IP routes around damage. It wasn't a fire at a facility which caused an outage, it was incorrect network design.

Sometimes fire equals kill all power also are you going to tell the firemen we can't push the big red button
Primary power = Commercial AC
Secondary = Generators
Battery strings and rectifiers in that mix somewhere. Trivia: Many telco systems are DC. Usually -48v
Lightning strike probably destroyed batteries and / or rectifiers meaning even IF the generator came out unscathed, it would not matter.
If it is a building that housed a pass-through fiber node, it will not take long to reroute it.
If it is a fiber drop / handoff point, may take a bit longer but AT&T will roll their mobile crisis units out ( essentially 18-wheelers loaded with routing, switching and fiber hardware that can be sent just about anywhere with short notice ). Think of them as a mobile Central Office.
I know we all like to hate on AT&T but I guarantee there is an army of folks on site doing everything they can to restore service.
Right, they should have had completely redundant wiring for the two power sources, not just two power sources for the facility.
At some point your redundant systems have to converge.
If your company has two ISP connections, diversity of service, they likely have both routers in the same rack in the same closet.
But no, you're right, they need to put two power rooms on alternate sides of the building, with both running to a third room, where there is a cutover in case one fails... oh wait, what if that room catches on fire? I guess they need to run parallel wiring to every outlet....
Your fantasy of how to set up a redundant system has no place in the IT industry.

Since you seem to know what you're talking about (or falling it pretty good), let me ask.. and please excuse my ignorance if I don't know what I'm talking about: Aren't lightning rods designed to attract lightning away from "sensitive areas"? I know there are lightning rods mounted on most (all?) major communications towers to avoid damage from lightning. If that is the case, wouldn't that have also prevented this from happening to the AT&T facilities?
There are large copper unshielded grounding cables in telecom rooms. A lightning strike wouldn't cause a fire, rather it's the reverse, there likely was a failure to to ground something, and the lightning came in on whatever that was. Probably a wireless antenna.
experience level: I've been in the telecoms room at my office building making a report of all the stupidity in it.
there likely was a failure to to ground something, and the lightning came in on whatever that was. Probably a wireless antenna.
Seriously? Why would there be a wireless antenna there?

no internet access right now.
Actually, yes. Our specs called for Power from "A" to run through the "A" generator panel and the left side of the rack. "B" ran on the right. We'd have to have a power event take out the automatic transfer switch for BOTH A and B (opposite sides of the building) to knock the entire facility offline.
Now a fire in the rack.. that'll take down that rack. But this design is in building redundnacy 101.
Hmm. Out-of-band management connection, GPS antenna for providing 1PPS timing services, microwave backup link...
