The betting exchange said its website proved “extremely resilient” during one of the busiest days in the horseracing calendar.
The Grand National day set new records for the site, including peak outbound bandwidth of 143Mbps (up from 110Mbps during this year’s Cheltenham Festival).
“This is thanks to the dedication of our staff,” said Betfair’s chief executive Stephen Hill.
Leading bookmaker William Hill managed over 25,000 concurrent online users, answered more than 112,000 telephone calls and accepted over 300,000 individual bets across the day.
To make sure its website was not slowed down by punters setting up new accounts, William Hill operated a sister site which handled 30,000 new account registrations.
