The MrBeast camp has blamed the recent CrowdStrike outage for the terrifying experience people endured during filming of the Beast Games in Las Vegas last month. Participants were reportedly injured and assaulted, while others were reportedly denied their personal medication for extended periods of time while the competition was underway.

Participants spoke about their experiences at Allegiant Stadium on July 18 for the Beast Games, a new television show hosted and run by MrBeast in partnership with Amazon. An Aug. 2 New York Times report included comments from several participants who spoke anonymously to avoid violating contractual confidentiality agreements. Many described the conditions as poor, including inadequate meals and medical care, but a spokesperson for MrBeast said many of the problems were beyond their control.

“[The event] was unfortunately complicated by the CrowdStrike incident, extreme weather conditions, and other unexpected logistical and communications issues,” the spokesperson said in a recent text message to The New York Times. A follow-up message added that MrBeast had launched a “formal investigation” and that steps were being taken “to ensure we learn from this experience.” Amazon MGM has not yet issued a formal statement.

The CrowdStrike incident last month crippled technology and communications worldwide, affecting more than eight million computers worldwide. The incident coincided with Beast Games, which saw 2,000 people compete in a preliminary round of the show. The top 1,000 competitors advance to the Amazon show, while the July 18 taping was largely filmed for MrBeast's YouTube channel.
