WASHINGTON – Popular smartphone messaging application WhatsApp was restored hours after it faced global outage creating stress and panic among tech savvy buffs.

The messaging application owned by social networking giant Facebook went offline globally late Wednesday without providing any clue as to what caused the massive shutdown on all the mobile platforms including Android and iOS.

However, the company restored the services in a short period of time and apologised for cutting millions off without revealing the reason for the brief termination of services.

“Earlier today, WhatsApp users in all parts of the world were unable to access WhatsApp for a few hours. We have now fixed the issue and apologize for the inconvenience,” WhatsApp said in an email.

Quite ironically, the outage came hours after Mark Zuckerberg, the CEO of Facebook and Whatsapp announced quarterly results of his conglomerate.

WhatsApp is used by more than 1.2 billion people around the world, successfully managing to replace traditional text messaging in many countries. The service was acquired by Facebook in 2014 for a staggering $19 billion from an I.T expert who was refused a job at Facebook, some years back.
