Blockbuster was the first to glitch, with Pingdom reporting the entertainment site becoming unresponsive at 1:43 PM New York time and staying down for 18 minutes. It was reported back down again at 3:11 PM New York time and it stayed down for 32 minutes. It then was reported down again at 3:57 PM and stayed down for 11 minutes.
Another prominent Web site monitoring service, Dotcom-Monitor, also reported the initial Blockbuster outage (at about 1:45 PM Friday, New York time), but it did not detect the others.
Blockbuster's troubles continued into Saturday (Aug. 29), with Pingdom reporting a half-dozen more Blockbuster.com outages.
Dotcom-Monitor saw significant problems with Walgreens.com, starting at 2:24 PM Friday (Aug. 28) New York time and lasting for more than two hours, ending at 4:37 PM. Dotcom-Monitor reported a very brief outage from Walgreens on Saturday morning (Aug. 29) as well.
The Walgreens problems resulted in a series of timed-out page requests along with "unable to connect to the remote server" issues.
