After four days of suspension, Pakistan Telecom Authority (PTA) restored the internet service in different cities of the country on Friday night.

According to the 24News HD TV channel, the internet service in Lahore, Islamabad, Karachi, Jhang, Toba Tak Singh, and other regions has been restored.

The government suspended the internet service in all the major cities of the country on May 09 after the arrest of Imran Khan in Islamabad.

Twitter, Facebook and Instagram's services are reportedly down for many users in Pakistan as they are unable to access the popular social media platforms on May 9 evening.

According to the outage-tracking website, Downdetector.com, users are unable to log in to their accounts on all three platforms, meaning they also couldn't post or view anything.

Downdetector tracks outages by collating status report from a series of sources, including user-submitted errors on its platform. The outage could have affected a larger number of users.

A large number of smartphone users are also complaining about their WhatsApp which is not working both on desktops and cellphones.

Moreover, as per reports, internet speed is also slow for many users across the country.

The partial suspension of social media platforms and WhatsApp came soon after workers and followers of the Pakistan Tehreek-e-Insaf (PTI) are holding countrywide protests following party chairman Imran Khan's arrest in the Al-Qadir Trust case.
