With a boost from the Drudge Report, the Chron’s SFGate.com had its busiest day ever Thursday after breaking the story about Mayor Gavin Newsom’s affair with the wife of his campaign manager. SFGate.com had 4.8 million page views for the day, beating its previous high of 4.4 million on Election Day 2006. But the site had a slowdown Thursday morning after the Drudge Report added a link with photos to the SFGate.com site. “He caused a little traffic jam for us and we asked him to remove it,” SFGate’s Peter Negulescu told E&P. “It slowed the response time, but we never crashed.”
