Michael Jackson's death on Thursday caused a spike in visits to news Web sites that affected the performance and availability of some of the biggest ones, according to Web monitoring company Keynote Systems.

Michael Jackson's death on Thursday caused a spike in visits to news Web sites that affected the performance and availability of some of the biggest ones, according to Web monitoring company Keynote Systems.

Between 6 p.m. and 8 p.m. U.S. Eastern Time, the availability for the news sites from ABC, CBS and the LA Times dropped to almost 10 percent, meaning that about nine out of 10 visitors couldn't get the sites to load.

Starting at 5:30 p.m., the average download speed for news sites tracked by Keynote went from less than four seconds to almost 9 seconds, and their average availability dropped from almost 100 percent to 86 percent, the company said. News sites monitored by Keynote returned to normal performance and availability levels by 9:15 p.m.

Other news sites that experienced problems included AOL, MSNBC, NBC, the San Francisco Chronicle and Yahoo News, according to Keynote.

However, in a subsequent statement late Friday evening, Keynote noted that the slowdowns were caused primarily by external providers of interactive images and ads to the news sites. An example was the news site of ABC, which served up its internal content without delay but got dragged down by its external providers, Keynote said.


In these situations, depending on how a Web site is designed or how end users' browsers are configured, Web pages can display immediately their internal content, leaving blank sections for the delayed external content or, at the other extreme, the pages will not be displayed until all components are ready to be rendered, according to Keynote.


"Ongoing end-to-end load testing and performance measurement benchmarking are essential to being prepared for unexpected news events. News sites should require third party content companies, such as ad networks, to certify the capacity of their networks, perform regular load tests from around the globe, and have strong Service Level Agreements in place," Keynote said in its statement Friday evening
