There seems to be a major site wide issue with MySpace that looks like it started November 18th and is still ongoing.
Looks like it has to do with events.json and causes any page on MySpace to grind to a halt freezing Firefox/Chrome browsers.
Here is an example link that gets pinged, http://318.webim0249.webim.myspace.com/api/v1/events.json, through Firebug it looks like 9 open connections are made.
Is this being looked into?
