Scopus has been experiencing issues with its Alerts system since December 28, 2015. This means that no Alerts have been sent since the 28th. The root cause of the issue has been identified and the Alerts are currently being re-processed. We expect all systems to be working properly within the next 24 hours. We apologize for any inconvenience this might have caused and we will update this post (and social media) when the issues are resolved.
