The present disclosure relates to network connectivity and reachability monitoring in cloud environments. In an example, a computer receives, from a device of a customer, input indicating a destination that belongs to a virtual cloud network and a set of vantage points for testing the destination. Based on the input, a first source is deployed to a first network location associated with a first vantage point and a second source is deployed to a second network location associated with a second vantage point. Each source is configured to send probes of different types to the destination. The computer system receives, probe data from each source based on probes sent by the source to the destination. Based on the received probe data, the computer system generates test data indicating at least one of connectivity or reachability of the destination. The test data is presented at a user interface.
