A petition calling for Theresa May to cancel Brexit by revoking Article 50 has passed two million signatures.
Parliament's petitions committee tweeted that the rate of signatures was "the highest the site has ever had to deal with", after the website crashed.
EU leaders in Brussels have reached agreement on a plan to delay Brexit beyond 29 March.
Downing Street said the prime minister "has said many times she will not countenance revoking Article 50".
The PM's spokesman added: "The PM has long been clear that failing to deliver on the referendum result would be a failure of democracy and failure she wouldn't countenance."
