The Network Had Bandwidth. The Application Was Still Starving: RFC 1453
A fast network can be perfectly real and completely irrelevant to the frozen face on a conference screen. In 1993, RFC 1453 located that contradiction inside the machine: capacity had reached the link, perhaps even the transport, while buffers, operating-system paths and…

Flex Has a $4.4bn Bridge for a $4.4bn Deal, Not SpinCo’s Final Balance Sheet
The acquisition price, the temporary funding ceiling and the planned separation sit on three different clocks. Investors still need the permanent financing and allocation record that connects them.

Rohan Mahy and the Certificate Purpose That Did Not Deliver an Instant Message
An IM certificate can say that a key is meant for an instant-messaging identity. That narrower purpose is useful security design. It does not say that an application submitted a message, that a service accepted it, or that any person received and read it.

Neil Jenkins and the StateChange That Did Not Audit a Mailbox
A JMAP client that sees a new state string has learned something important: its local view may no longer match the server. That is a signal to synchronize. It is not, by itself, a record of which message changed, which mailbox moved, which principal made a request, which policy…

A Signature Is Not Proof of the Other Key: RFC 9883 and Private-Key Possession Statements
A second certificate request can be validly signed by an already certified signature key, yet that signature is only an assertion—not technical proof—that the requester controls the different private key behind the requested key-establishment certificate. RFC 9883 defines how a…

The Packet That Had to Answer Back: TCP's Challenge ACK Repair
TCP once treated a reset that landed anywhere inside the receive window as sufficiently believable to tear down a connection. RFC 5961 replaced that destructive shortcut with a narrower rule: exact sequence alignment could act immediately; merely plausible input had to survive a…

The ACK That Could Not Say Which Packet Arrived: Karn's Retransmission Ambiguity Rule
The same sequence range crossed the network twice. The acknowledgment that returned proved the bytes had arrived, but not which transmission had earned the reply. Karn's rule turned that uncertainty into a discipline: delivery evidence could advance while the round-trip estimator…

A Ghostbusters Record Is Not an Incident Command Roster
An RPKI relying party can validate every byte of a Ghostbusters Record and still not know whether anyone is watching the listed channel when action is needed. The signed entity solves discovery of minimal CA-maintainer contact data; operational accountability begins where that…

The Signature Algorithm Is Not the Signed Byte Sequence: RFC 9882 and ML-DSA in CMS
Two CMS systems choose ML-DSA-65 for identical content, yet verification fails when one signs a final implicit-tag representation and the other verifies the complete DER SignedAttrs value with its explicit SET OF tag. The algorithm is the same; the signed byte domain is not.

AFRINIC Deemed Two NRO NC/ASO AC Candidates Elected Unopposed. Its Linked 2026 Rulebook Now Returns 404
AFRINIC’s final 2026 candidate slate said Stephen Musa Honlue and Nitin Kelawon Sookun would be deemed elected unopposed to the NRO NC/ASO AC, while voting would still decide the duration of their terms. The Election Guidelines page linked as the basis for that procedure returned…

A Trust Anchor Rollover Needs an Acceptance Ledger
An RPKI trust-anchor operator can publish a successor key without making every relying party ready to use it. The transition is a sequence of verified observations, not a launch date: a defensible record must show what was announced, what remained stable, which validators crossed…
History
The Packet That Waited for Its Predecessor: Nagle's Small-Segment Rule
A one-byte write did not need a universal delay timer. It needed a rule about whether the connection already had data in flight. Nagle's answer made acknowledgment state—not the wall clock—the gate for another short TCP segment.

The Algorithm Name Is Not the Certificate Profile: RFC 9881 and ML-DSA in PKIX
The Algorithm Name Is Not the Certificate Profile: RFC 9881 and ML-DSA in PKIX intelligence summary explains the development, the public evidence available to readers, the organisations involved, the regional context, market exposure, and the infrastructure consequences that may…

AfNOG Publishes Mailing-List Rules, Not the Moderation Procedure Behind Them
AfNOG’s mailing-list page sets clear expectations for a technical community: keep discussion operational, avoid disrespect, and do not use the list for blatant product marketing. The published page establishes the rules. It does not explain the procedure used when a post is…

An RPKI Publication Point Needs a Commit-to-Visibility Ledger
An RPKI publication server can accept an authenticated update atomically while relying parties still hold an earlier repository view. That is not necessarily a contradiction or a failure. It is a boundary between different authorities, protocols and observation times. A useful…

A Registry TTL Is Policy State, Not a Live DNS Observation
RFC 10037 lets a registry publish configured DNS time-to-live values through RDAP. That sounds like a small JSON extension. Its more important effect is to expose a piece of registry policy without pretending that a registration-data service is watching the live DNS. The…

A Data Model Is Not a Wire Contract: RFC 9880 and SDF Protocol-Binding Boundaries
Two implementations can claim the same Thing model yet disagree on the wire: one chooses a URL and JSON payload convention, while the other expects a numeric identifier and different invocation rules. The gap appears when a protocol binding was implicit rather than versioned and…

The Probe That Could Not Declare an Idle Peer Dead: TCP Keep-Alives
An idle TCP connection can be quiet without being broken. Keep-alive probing was designed to ask whether the peer's transport state could still answer, while denying any single unanswered probe the authority to declare that state dead.

A Hybrid SSH Key Exchange Turns Algorithm Negotiation into a Migration Boundary
Installing post-quantum code does not mean an SSH session used it. RFC 10042 defines three hybrid methods that combine ML-KEM with an established elliptic-curve exchange. The protection becomes real only when both peers offer the same method, negotiation selects it, both…

Prasad Vadke and the Escalation Clock Behind Enterprise Email
An enterprise email incident starts two clocks at once. One measures the technical work of diagnosis and recovery. The other measures missed decisions, interrupted meetings and the widening cost of uncertainty. Prasad Vadke's public writing on service-level agreements is most…
