A December 16, 2007, money bomb on the anniversary of the Boston Tea Party broke the campaign's previous record, raising nearly $2 million more than the November 5 event, bringing in over US$6 million in the largest single day of fund raising, on-line or not, in U.S. presidential campaign history. During the last minutes of the drive, the server refused to accept contributions due to an overload of donations, as about 100 contributors per minute donated to the campaign; more than an additional $100,000 were donated within the hour past midnight.
