Mobile phone networks also blocked access to the social media platform.
The move came after Twitter deleted a tweet by President Muhammadu Buhari for breaching the site’s rules.
Some users saw his post, which referred to Nigeria’s civil war four decades ago, as a veiled threat towards a secessionist movement in the south-east of the country.
The Nigerian Government said the tweet’s removal was “disappointing”.
The Government said: “There has been a litany of problems with the social media platform in Nigeria, where misinformation and fake news spread through it have had real-world violent consequences.”
The Nigerian Government has toyed with the idea of regulating social media sites since the current administration came into office in 2015.
Deleting the president’s tweet was seen as the final straw.
