We have a selective peering policy and evaluate each request based on its merits. We also require from our peers: * common sense * must filter customer prefixes strictly * must not leak prefixes from non-customer sessions (even if the prefix is from a customer) * an updated peeringdb entry * reasonable prefix aggregation * responsive NOC * peers IX-link must not be congested * IPv6 peering, if peer AS is v6 enabled * must not be our customer, or a customer of a existing peer * do not send automated emails to our NOC for whatever reason; humans only! Peering through route servers is usually preferred over dedicated BGP sessions, especially for low-volume, low-prefix peers that are already connected to the route servers. This is to avoid unnecessary maintenance and configuration overhead. We filter all our customers with strict prefix-lists (along with other industry standard filtering and security measures), no exceptions.
