Instagram, other sites go down

AirBnB says its site was one of those affected. Other services that were slow or unavailable included Instagram and Twitter's Vine video-sharing application.

Online home rental service AirBnB tweeted at 4:32 p.m. ET that it was one of several websites and apps that were temporarily down because Amazon server problems.

Instagram sent a tweet saying it was aware some users were having trouble loading Instagram and that was working on the problem. Vine later sent a similar tweet.

Amazon Web Services provides companies with online storage and computing power. Its website showed several problems resolved on Sunday evening, with a few remaining.

Amazon did not immediately respond to a request for comment.
