Never underestimate the power of a boyband.

Park Chanyeol, a member of the Chinese-South Korean group EXO, is being held responsible for a website crashing.

The incident is said to have occurred when the 22-year-old directed millions of his followers to a TV show's website, causing it to buckle under the demand.

Fans just couldn't wait when the hitmaker told them that he'd released a video on the SBS website ahead of his appearance on their 18 seconds variety show.

Taking to Instagram, he wrote: "Everyone~Please look for the video I uploaded on the '18 Seconds' homepage."

The traffic reportedly got so much that the SBS website's name quickly became one of the most searched for items on search engines.

The brief video featured Park Chanyeol making a milkshake from scratch.

Luckily for his admirers, it's now been uploaded to YouTube to be binged on as much as their hearts desire.

EXO have been together since 2011 and appear to be China and South Korea's answer to One Direction.
