One plane was kept on the tarmac for 90 minutes this morning with passengers being told there had been a 'country-wide systems failure'.
The budget airline confirmed the outage resulted in disruption to airport check-ins and boarding.
It caused disruption at airport check-in desks across Europe.
Graeme Jolly tweeted: "confusion, chaos and absolute carnage right now at the check-in/bag drop desks at Rome Ciampino. 20minutes so far and no closer to desks. Totally unacceptable."
Another passenger quizzed the airline about a flight taking off.
Romana McCallum wrote: "Why is a flight allowed to leave when the boarding system crashes mid-boarding, leaving passengers at the terminal?
"Only 3/4 of our party made it through and the remaining 1/4 are stuck at Stansted. Utterly irresponsible, expensive and huge waste of time: Why?"
Vicky Graham-Stevenson complained to Ryanair on Twitter .
She said: "can you please tell me why my daughter has just been charged £55 to check in at the airport when she hasn't been able to check in online due to the website keep kicking her out every time she tried".
One passenger on a Stansted to Faro flight told Mirror Online: "Basically we've been on the tarmac for 90 minutes and they say it's a country wide system failure.
"I've seen people on twitter saying they're stranded".
A spokesman for Stansted Airport said: "There was a short disruption to some of Ryanair's systems earlier today at Stansted.
"No other airlines have reported problems this morning."
Shortly before 8am another passenger tweeted: "is your online check in down? Its saying our booking cant be found and were trying to check in for our flight home tomorrow..."
At roughly 10.30am a Ryanair spokesman said: "This morning we suffered a system outage which caused some short delays at airport check-in and boarding.
"The system has been restored and flights are operating as normal. We apologise for any inconvenience caused".
Ryanair states on its website that people who do not check-in online will be charged £55 per passenger to do so at the airport counter.
