Claim 12:
13. One or more computer-readable non-transitory storage media embodying instructions that, when executed by a processor, cause the processor to perform operations comprising:
identifying a problematic event between a first interest point and a second interest point of a network, wherein the first interest point is associated with a first cloud provider and the second interest point is associated with a second cloud provider;
activating, in response to identifying the problematic event between the first interest point and the second interest point, a first endpoint associated with the first interest point and a second endpoint associated with the second interest point, wherein:
activating the first endpoint and the second endpoint initiates a generation of Operations, Administration, and Maintenance (OAM) out-of-band data packets by the first endpoint and the second endpoint; and
each of the OAM out-of-band data packets uses an OAM packet format, the OAM packet format comprising:
a Media Access Control (MAC) header;
an EtherType;
an Internet Protocol (IP) header;
a User Datagram Protocol (UDP) header;
at least one cloud OAM option; and
a Cyclic Redundancy Check (CRC);

receiving, from the first endpoint and the second endpoint, telemetry data associated with a problematic path between the first interest point and the second interest point, wherein the telemetry data comprises an identity of the first cloud provider, an identity of the second cloud provider, and an identity of one or more cloud regions; and
determining the problematic path between the first interest point and the second interest point using the telemetry data received from the first endpoint and the second endpoint, wherein the telemetry data is collected by the OAM out-of-band data packets.
