Social media users have been flocking to Twitter in reaction to Facebook, Instagram and WhatsApp outages, which have lasted several hours.

The three services, all owned by Facebook, could not be accessed via the web or smartphone apps.

Twitter and Reddit were among several tech companies poking fun at their rivals.

The affected services had to take to Twitter themselves, as fun and serious messages burgeoned.

Hi and happy Monday 😵‍💫

Major names from the world of entertainment, including Dolly Parton, have been getting in on the fun.

Others have been joking about seeing dormant Twitter accounts bursting into action again.

But Twitter may have started to smirk at its rivals prematurely, as many of its users started experiencing problems, with the Downdetector site showing a peak of outage reports at about 19:30 GMT.

Some, including whistle-blower Edward Snowden, have been using the outage to make a more serious point.

Facebook-owned Whatsapp being down is a reminder that you and your friends should probably be using a more private, non-profit alternative like @Signalapp anyway (or another open-source app of your choice).

It's just as free, and takes like 30 seconds to switch.#facebookdown

And others have been tweeting about how the outage is a good thing.

Retweet if you think it is a good thing for society that Facebook is down.
