Twitter REST API hangs and returns no result since Friday pm 20/11/15



I have a Ruby application using the twitter gem to search tweets using the Twitter REST API.

Since Friday afternoon 20 Nov 2015, I haven’t been able to get any results back. My program has been working until then.

The program hangs and either is killed or returns with error:
Twitter::Error::TooManyRequests: Rate limit exceeded.

I know there’s a limit that I can make a search request once every 15 minutes. But since Friday afternoon, I can’t make any requests. In other words, all requests fail with the error “rate limit exceeded”.

Is the Twitter REST API down? Or is it a problem with my account (eg access token issue)?

Please advise. Thank you.
