Amazon.com Inc's platforms, including its online store website and Amazon Web Services, were down for multiple users late Sunday, according to outage monitoring website Downdetector.  More than 3,700 user reports indicated problems with Amazon's online store site, while about 280 users reported problems with Amazon Web Services, according to Downdetector.

The issue affecting the sites was not immediately clear. Amazon did not immediately respond to a Reuters request for comment. About 80% of the problems reported were with its website, while 15% was with its log in and 5% with its check-out, according to Downdetector.

Downdetector tracks outages by collating status reports from a number of sources, including user-submitted errors on its platform. The outage could have affected a larger number of users.
