Long Zheng: Over the last few days I’ve noticed Digg.com has slowed to a crawl where it would take up to a half a minute to load each page. At first I thought it was Digg, but then I noticed “connecting to ads1.msn.com” in my status bar when apparently nothing would happen. Is there something wrong with Microsoft’s advertising network?
One of the many neat features in Firebug - a web-developer extension for Firefox - allows the monitoring of network traffic when loading a web page. This is extremely useful to track down causes for slow loading websites.
