The rule-of-thumb for WAN (internet-facing connections) is 100Mbit/s of 24/7 usage per every 4GB of memory with a purchased slice. We do, however, allow our customers to “burst” their usage up to 1Gbit/s during times of lower network use across the entire node. Internal (private) networks do not have these bandwidth limitations, and can take advantage of our 40Gbit/s LAN for routing traffic between slices within the same datacenter.
