Global Warming and MySpace

MySpace has been down for a day or so now, the victim of a power outage at its data centre (according to a comment on GigaOM, this facility). This is presumably the same power outage that took Dreamhost down on Saturday. Power outages seem to be increasing in frequency, particularly in air conditioning season. Are we seeing the result of the increasing strain put on the grid by the progressive effects of Global Warming? An interesting situation to be in, as everything moves on to the Web.
