We'll respond shortly.
As some of you have (painfully) noticed, we’ve been having problems with our CDN (content distribution network), causing slow or failing loads of certain Tracker “assets” including images and style sheets. This is affecting users in certain locations only – over the weekend it was South America and certain US cities, while this morning it seems to be mostly the east coast and parts of Canada.
We’re terribly sorry about this, and know how disruptive not being able to get to your projects can be. Our hosting provider is on top of this, and has escalated this to the highest level with the CDN vendor. The issue appears to be related to network congestion in a particular CDN ‘node’, they are working to replace it and route traffic around it, temporarily.
Also, we’re actively looking at moving to a different CDN provider, and/or eliminating the need for CDN use by reducing the number of images/etc that need to be loaded in the app.
We’ll post updates as we get them via Twitter, please follow @pivotaltracker to get the latest.
