With Republican Donald Trump inching closer to what could be the biggest electoral surprise in US history, the immigration website of neighbouring Canada has crashed multiple times, according to reports.

The website displayed "internal server problem" notification multiple times during the night, triggering speculation that Americans are visiting the site in huge numbers even as a Trump presidency appeared likely.

Donlad Trump has taken a a clutch of key swing states in a big surprise, leaving Hilalry Clinton's fate to hang in balance tonight.

Visitors trying to access the site get the internal server error message.

In another coincidence, the search term emigrate jumped in frequency around the same time the website crashed, the Telegraph reported.

This could be a coincidence for all you know, but in the heat of the divisive. brutal and brusing election campaign many prominent US public figures had taken a public, if polemic stance that they would leave if Donald Trump wins the US election 2016.
