This isn't the first time E-tail updates have wrecked havoc with uptime tracking systems, as 1-800-Flowers discovered in February. Exactly what Amazon changed to confuse Pingdom's bots isn't clear; Amazon wouldn't comment. And in fairness, it's not an E-tailer's job to play nice with monitoring services. But something at Amazon continues to drive monitoring sites a little crazy. On July 1, after the Pingdom problem was cleared up, there was a rash of Twitter reports that Amazon was down. They were based in part on the popular downforeveryoneorjustme.com site, which reported: "It's not just you! http://amazon.com looks down from here." As of tonight, that site still thinks Amazon is down.
