Local law enforcement agencies asked witnesses to stop calling 911 to report the meteor, saying they were tying up the phone lines.

“There is no need to call 911, it’s a natural meteor fireball,” the Ingham County’s Office of Homeland Security and Emergency Management said in a Facebook post.

This event sparked so much interest that people coming to AMS website managed to crash it.

“Major event in Michigan. Server is getting overloaded. We’ll be back ASAP, check back soon,” AMS said and directed users to submit their reports to the International Meteor Organization (IMO). Since IMO and AMS share reports received, there was no fear of lost reports.
