The company continues to deny that the issue was caused by a hack or attack, with a company spokesperson telling CNN Business that it was focused on resolving the issue and hoped to eventually share more details about what caused the almost 24-hour blackout.
On Thursday, Facebook blamed its lengthy outages over the past day on a "server configuration change".
"We're very sorry for the inconvenience and appreciate everyone's patience", Facebook said.
Facebook suffered a huge outage starting on Wednesday that affected users worldwide.
"As people become more reliant on digital services like Facebook, Instagram and Youtube, we are witnessing an ever growing number for problems during outages", Sanders said.
Thousands of users took to Twitter over the past day to complain about the outage, causing the hashtag #facebookdown to trend. Durov's announcement doesn't mean that three million people have abandoned Facebook, but don't underestimate the network effect if newcomers find they like Telegram and encourage their friends to join.
Facebook took to its Twitter account Wednesday to assure users that the outage wasn't due to a "distributed denial of service" attack, or DDoS, meaning the disturbance wasn't the result of hacker attacks. Beyond Instagram's tweet, Facebook has provided no further updates in the hours since then.
"We really don't know anything, and at this time, that's fascinating in and of itself", Patterson said.
The New York Times recently reported that Facebook is putting a ton of resources into its own blockchain-fuelled payment system that could help it mitigate its reliance on advertising as its dominant source of revenue.
Shares of Facebook were down more than 1.5 percent Thursday morning. The company has a large campus of data centers in Prineville.
According to the report, a grand jury in NY has subpoenaed information from at least two major smartphone makers about such arrangements with Facebook. And Spotify and Netflix reportedly were allowed to see user private message information.
