A system and method are presented for analyzing network performance of a web application. A user interface in a cloud-based collaboration platform provides a notification when the user's location is having network connectivity issues to the collaboration platform. Connectivity issues may be determined through aggregation of measurements of network quality and performance (e.g. XMLHttpRequest requests, Websockets, and WebRTC) and alerting the user when issues arise. Data may be pushed back to an analytics ingestion system for aggregate-of-aggregate analytics and alerting as well as viewing network performance across a plurality of users and organizations.
