To the ire of many, YouTube went down Friday. At the time this article was written, it was unclear why the site wasn’t working.

If people tried to log on to YouTube.com, they saw a “500 internal server error.”

“Sorry, something went wrong,” the message read. “A team of highly trained monkeys has been dispatched to deal with this situation. If you see them, send them this information as text (screenshots frighten them).”

Listed below was a block of code. A picture of purple monkey wearing a red hat and a hammer in hand appeared on the right side.

Twitter users quickly took to the 140-character social media blog to complain about YouTube being down. “Red alert. @Google's @YouTube is down for parts of the world. This is not a drill! #FridayFeeling #endoftheworld #FirstWorldProblems,” one person wrote. “LOL @YouTube  is down...got some monkeys on it hmmmm,” another said.

YouTube did not immediately issue a statement.

For some users, the streaming service worked on their phones, but not their desktop. The same went for laptops versus desktops.

According to DownDetector.com, more than 6,000 people reported having problems with YouTube.com around 9:00 a.m. EDT. “YouTube is having issues since 9:06 AM EDT. Are you also affected? Leave a message in the comments,” the statement on the page read.

The stats on DownDector.com claimed more than 60 percent of people had problems viewing videos, 27 percent of people had problems accessing the website and 11 percent of people had trouble logging in.

This isn’t the first time YouTube went down. The last time it crashed was two weeks ago, and another time in February.

The problem was seemingly nationwide, with people in the comment section writing what states were still experiencing problems, and which states it was working. “Welcome to the YouTube is Experiencing Technical Difficulties party. We have food, drinks, movies, and reruns of the Super Mario Bros. Super Show and the Zelda cartoon for everybody,” netizen TheZeldaCartoonLink wrote.

Nearly 20,000 people flooded the comment section.

Outside the U.S., there were problems reported in the U.K., too, the Express wrote. At one point, there were as many as 15,000 people experiencing problems with YouTube.
