Canada's main immigration website appeared to crash and New Zealand reported increased traffic from U.S. nationals as Republican presidential candidate Donald Trump appeared likely to win the White House on Wednesday.

Canada's main immigration website appeared to suffer repeated outages Tuesday night as Trump took the lead in several major states and his prospects for winning the U.S. presidency turned markedly higher.

In New Zealand, immigration officials said on the eve of the vote that the New Zealand Now website, which deals with residency and student visas, had received 1,593 registrations from United States citizens since Nov. 1— more than 50 percent of a typical month's registrations in just seven days.
