Combination of loss of a lot of connectivity in New York, with massive amounts of increased load on the databases of sites from everyone wanting to know what was happening

It was nearly 20 years ago, but from memory the BBC did load occasionally, really really slowly

CNN had to revert to a bare bones HTML page because their servers and Internent connection couldn’t handle the load of everybody reloading as things unfolded.
