Neither one is very accurate for advanced cancellations--especially as DL may not have completely worked out their schedule for tomorrow yet. Neither site is updated minute-by-minute either in regard to cancellations and delays. Flightaware is great for real time tracking. Flightstats gives less updates when the flight is in the air. Flightstats tends to be a bit more reliable in calculating cancellations and delays but that data may only be updated once an hour.

Plus you don't really care about every flight. You only care about the 2 you are on:) Delta could run every flight on time and cancel 1 of the 2 you are taking and your plans would be messed up.

Any thoughts on when DL will be back to 100%? I'm thinking late Thursday at the earliest.

Don't they have a site B??

Old NW??

Yeah. They're saying all systems should be operational and as normal tomorrow. So, we'll just have to wait and see. In the meantime, expect more cancellations.

I'd be pretty surprised if they're back up to 100% by Thurs. I wonder how many more flights will be canceled or delayed due to operational issues on Wed.

The central office, no. The rest of the system? You betcha it did.

January 15, 1990: AT&T went down hard. Initial sensationalistic media reports blamed computer hackers, claiming they had broken into AT&T's systems and crashed the phone network. In reality, though, a new software update to AT&T's 4ESS long-distance switching system was the culprit: a self-test routine intended to let a switch recover from a fault instead triggered a fault condition in other switches when it sent out the "I've recovered" message. The fault-triggering signals echoed back and forth across the network, taking switches down, and then they'd come back up and broadcast the "I've recovered" message which would take down another wave of switches... and continued to do so for roughly nine hours before engineers were finally able to stabilize it.

Was Delta's outage yesterday unfortunate? Yes. Was it unprecedented? No. Was it the kind of thing that's worth the cost and effort of making impossible? No.

I can see there being passengers still waiting to travel. However as for flights departing on time/getting cancelled I highly expect that Thursday is realistic for being back at 100%. (Absent of course some freak weather or other incident)

They cancelled my Wednesday 9:10 flight from LGA to DTW. No option to re-book on app or desktop site. Phone lines ringing busy. What a mess... I am going to avoid Delta until Monday.

Yeah, Delta phone lines are slammed. When I called, they estimated 3-5 hours to give me a callback. It's been nearly 6 and I am going to bed. (Luckily my travel agent managed to get me rebooked.)

80% chance of thunderstorms in Atlanta tomorrow. Similar forecast in NYC.

That's probably the smart move. For all we know, there could be another system failure as they're trying to get everything back online. Data centers do not like outages and cold restarts.

Yeah, that's what I meant by "tin foil hat path" (in the context of this specific outage, not the world as a whole).

It's nice to see /. heading down the same path of "if I ran their data center, there's no way this would happen" that FT has already covered :)

I've been checking three trips daily before and now during the problems. One TPAC return trip, one a six segment mix of domestic and Canada and one round trip TPAC. All have been perfect.

... but likewise tempered by some sympathetic voices :)

I worked for a Minnesota company years ago that had business throughout the world, but most done in the U.S. I used to spend a couple weeks doing training in Canada several times a year and brought back the form to get GST tax rebate. I filled it out and sent it with my expense report. They didn't have a clue what it was and told me I could keep it. Several hundred dollars. Oh the good old days. ;);)

Congratulations on using the wiki for this. It is full of great information and exactly what's needed in this situation. Cheers!
