Peering and Transit
Within the Topic facet, Peering and Transit topic intelligence connects articles that share a specific subject, signal focus, or monitoring theme. The page gives readers a richer path through related reporting, source evidence, market actors, and infrastructure implications, with enough context to understand why the topic matters across company movements, governance decisions, regional exposure, and operational risk. Readers can compare recurring signals, affected organisations, public evidence, market context, service continuity, procurement, competition, compliance, and strategic planning questions behind the subject instead of stopping at a thin list of matching articles. It explains what the topic covers, which infrastructure actors or policies are involved, what evidence supports the coverage, and why the subject may matter for operators, customers, investors, and policy readers.

Four-Octet ASNs Expand the Namespace While Compatibility Still Rewrites the Path
Four-Octet ASNs Expand the Namespace While Compatibility Still Rewrites the Path intelligence summary explains the development, the public evidence available to readers, the organisations involved, the regional context, market exposure, and the infrastructure consequences that…

Center-invest: a routing object is not a resilience audit
A single public routing record can contain a strikingly complete resilience story: three upstreams, RPKI controls and regulatory framing. Center-invest Bank's record is useful precisely because it shows where a due-diligence checklist begins—and where proof still has to come from…

A BGP Shutdown Message Explains the Decision Without Delegating the Restart
A session can disappear before an email thread catches up. RFC 8203 lets an operator place a short UTF-8 explanation inside an Administrative Shutdown or Administrative Reset notification. The explanation can connect a protocol event to a maintenance record, but it is not an…

A BGP Large Community Carries a Policy Signal Without Granting the Sender Authority
A BGP Large Community can carry an operator’s intent across network boundaries in a form that still fits four-octet ASNs. That portability is useful precisely because it is not command authority. The Global Administrator identifies the namespace whose documentation gives a value…

PS Processing: an unobserved registered block is not spare capacity
An address range can sit in a registry without appearing in the same public routing view as its neighbours. PS Processing’s records show why the gap belongs in a reconciliation ledger, not in a capacity forecast.

Protelecom: two ASNs do not prove two failure domains
Two autonomous systems can make a network look diversified before anyone has shown that the underlying infrastructure is independent. Protelecom’s public records offer a compact example of why buyers should separate routing identities from tested resilience.

A Stale Graceful-Restart Route Is Not Forwarding Continuity
BGP Graceful Restart can keep reachability stable while a control plane returns. The stale route is useful continuity evidence only when the forwarding state it assumes is still viable.

BGP ADD-PATH Exposes Alternate Routes Without Delegating the Best-Path Decision
A conventional BGP neighbor normally sees one advertised path for a prefix, so a replacement makes the earlier alternative disappear from that relationship. RFC 7911 changes that visibility by attaching a four-octet Path Identifier to each advertised NLRI. The identifier keeps…

A Lower BGP MED Is Not an Ingress-Traffic Guarantee
A lower MULTI_EXIT_DISC can express where a neighbouring network would prefer traffic to enter. It cannot certify the receiving network’s policy, selected path, forwarding state or measured traffic.

Extended BGP OPEN Removes a 255-Byte Ceiling Without Making Every Peer Ready for More Capabilities
BGP speakers announce capabilities before they exchange routes, but the original OPEN message gives all optional parameters together only one octet of length. RFC 9072 removes that 255-byte aggregate ceiling by defining an extended encoding. The change creates room; it does not…

A BFD Session Up Is Not End-to-End Reachability
A green BFD session is valuable evidence that a particular provisioned path is alive under its negotiated test. It is not a certificate that every forwarding member, packet size, return path or application transaction works.

Treat-as-withdraw Contains a Malformed BGP Route Without Letting One UPDATE Reset the Session
A malformed BGP UPDATE once carried authority far beyond the routes it described: under the base error response, it could bring down the receiving session and remove every otherwise valid path learned across that adjacency. RFC 7606 narrows that blast radius. Where the receiver…

A Damped BGP Prefix Is Not a Diagnosed Fault
Route Flap Damping can make a noisy prefix disappear from an operator’s update stream. That silence is a local control action shaped by penalties and timers—not proof that the circuit, router, policy or origin behind the instability has been found and repaired.

A BLACKHOLE Community Requests Discard Without Granting a Neighbor Unlimited Routing Authority
A DDoS victim may need traffic discarded before it reaches a congested interconnection, but asking a neighboring network to destroy reachability is an unusually powerful request. RFC 7999 standardizes that request while surrounding it with prior agreement, prefix authorization…

A Completed Route Refresh Is Not a Policy Reconciliation
Route Refresh lets a network replay BGP reachability without resetting the session. The exchange can finish perfectly while the operational question remains open: did the intended policy revision reach the right routers, act in the right direction and produce the expected…

A Graceful Shutdown Community Declares Maintenance Without Taking the Neighbor's Routing Authority
Planned maintenance is a local decision, but the traffic it moves belongs to an interconnection. RFC 8326 gives one network a standard way to say that an EBGP path is about to disappear while leaving the neighboring network in control of its own route preference. That…

A GTSM Hop Check Is Not Peer Authentication
A packet that arrives with the expected TTL can be close enough to pass a routing safeguard without being cryptographically proven to come from the intended peer. GTSM is valuable precisely when operators preserve that boundary.
