The media reporting of this outage as occurring on May 7 is flat wrong. They're off by 4 days. Centurylink's network outage began at ~12:25 CST May 3 and ended at ~01:00 CST May 4. Following are the entries from my mail server log that show the start, end, and duration of the outage. Note the flurry of queued deliveries occurring after IP routing was restored at 01:02 May 4. You can clearly see there are no client connections between 12:20 CST May 3 and 01:02 CST May 4, about 12.5 hours. I called the DSL support line once at about 13:30 May 3 after performing local troubleshooting and eliminating local equipment as the cause. I received "all circuits are busy, please try again later." Receiving that message when calling a telco is like walking into a grocery store and finding the shelves empty. I instantly realized the severity of the outage, and gave myself the afternoon of May 3 off, knowing it wouldn't be fixed for many hours.
BTW, how does one go about modifying the headline? It needs to inform readers that the outage date/time in the referenced articles is wrong by 3 days.
