After bragging yesterday about TaxProf Blog’s recent traffic surge, the IRS’s release of its traffic stats (IR-2006-66) put me in my place:  On April 17, there were 3,385,936 visits to the IRS web site, peaking at 3,237 hits per second at 12:30 p.m.   From the Information Release:

The IRS Web site is one of the most heavily used sites on the Internet during the tax filing season. This week’s record usage follows a redesign of the Web site last fall that enhanced search capabilities and provided easier access to tools that help taxpayers and tax professionals. The American Customer Satisfaction Index level for the Web site has also increased this year.
