M-Lab hosts our servers, which we call “pods”, in Tier 1 data-centers, connected to the Internet with links between 1-10 Gbps. In major metro areas, M-Lab strives to maintain multiple pods, each connected to as many distinct transit providers as possible. You can view where M-Lab servers are hosted on our platform status page.
Once an M-Lab pod is online we make no changes in our systems for the life of each pod. Whenever there is a substantial change to our sites, such as renumbering of IP addresses, we retire the pod, retain its naming and metadata in our systems, and treat the pod as brand new.
