Here is the statement from CrossFit
“The CrossFit Games site is currently experiencing service outages.
Amazon Web Services, which hosts much of CrossFit’s web infrastructure, started experiencing outages at 9 a.m. These outages have taken down the Games website, Quora, Airbnb, Medium, Business Insider and more than 120,000 other websites that utilize AWS.
As a result, the deadline to submit your score for Open Workout 17.1 has been extended to Wednesday, March 1, at 5 p.m. PT.
We appreciate your patience and apologize for the inconvenience.”
