SAN FRANCISCO—Many web users were trapped without service Monday, when a large section of the Internet collapsed under the weight of the millions of baby pictures posted online. "Some personal web pages contain literally hundreds of adorable infant photos," MCI senior vice-president Vinton Cerffe said. "Add to that the number of precious pumpkins on photo-sharing sites like Ophoto.com, and anyone can see it was a recipe for disaster. The Internet simply was not designed to support so much parental pride." Cerffe said he expects regular web-traffic flow to resume once the nation's larger Internet providers are reinforced with stronger cuteness-bearing servers.
