A massive computer system crash brought Disneyland and Disney California Adventure to a grinding stop with visitors not able to get in the front gates or use numerous technology-dependent functions at the Anaheim amusement park.

A blackout with the Disneyland Resort's ticketing system on Thursday, April 20 impacted the gates at Disneyland and Disney California Adventure, according to Disneyland authorities.

The computer problem was resolved in about half an hour and Disneyland cast members resolved any effects with guests on a case-by-case basis, according to Disneyland officials.

The system failure caught countless visitors in a "insane scene" outside the gates of the plaza in between Disneyland and DCA, according to Twitter user Kevin Penfold.

" Nobody new can be allow until system gets repaired," Penfold composed on Twitter.

Crazy scene @Disneyland thousands caught outside the entrance as ticketing has actually completely broken down. No one brand-new can be let in until system gets fixed.

" Bring persistence if you're on the way to Disneyland today," Rebecca Saryan composed on Twitter. "No one is entering at the minute."
