RFC 2067: The Standard Deleted Three Legal Packet Shapes
In 1997, Internet engineers advanced IP over HIPPI by making the specification smaller. Three packet forms allowed by RFC 1374 disappeared: a short burst could no longer come first, the D1 area could no longer contain fill, and the D2 offset could no longer be nonzero. RFC 2067…

A DTLS Return-Routability Probe Is Not a Migration Receipt
A protected datagram arrives with the right Connection ID and a new source address. The cryptography can locate an existing DTLS security context, yet the receiver still has a separate decision to make: whether to move that context, release application output to the new address…

Ward Christensen and the 128-Byte Agreement That Left the Ends Free
XMODEM became useful by declining to become a platform. Ward Christensen put a small, deterministic agreement on the line, then left almost every other decision—dialling, storage, filenames, interface and improvement—to the computers and people at either end.

AFRINIC’s Holiday Notice Appeared One Day Before Closure. That Is Not a 72-Hour Verdict
AFRINIC’s public record shows a 14 September notice for a 15 September office closure. Its service commitment speaks of seventy-two hours, but on a different channel: announcement mail. The right audit separates the website, the mail record, human response time and always-on…

The Orbit Said the Link Was Ready. The Network Had Not Agreed
RFC 9717 turns orbital predictability into a routing advantage without confusing a forecast with an observation. Its proposed satellite architecture can prepare for scheduled change, but a schedule, a computed SID list and even a successful install receipt remain different claims…

RFC 2066: The Character Set Was Already Right. The Reply Still Had to Arrive
Telnet had a rule for avoiding endless politeness: do not acknowledge a request for a mode already in effect. RFC 2066 made a narrow but consequential exception. A receiver already using one of the proposed character sets still had to send `ACCEPTED`, because silence would force…

Payoneer won the vote. Its shares still have not become $7.40 cash
The 224.99 million affirmative votes removed one branch of the Payoneer–Nuvei merger’s decision tree. They did not trigger the legal event that converts eligible shares into cash, settle the disclosure litigation or make the remaining regulatory perimeter disappear.

RFC 2065: The DNS Reply Crossed an Ordinary Server. Its Signature Carried the Trust
In January 1997, RFC 2065 proposed a security upgrade that did not require every machine carrying a DNS answer to become its judge. A security-aware resolver could retrieve signed records through a server that knew little about the new machinery and verify the evidence itself.…

Akvorado turns sampled flow records into operational network memory
Akvorado gives network operators a self-hosted way to retain, enrich and examine flow records over long periods. Its value lies in exposing the path from router export to operational decision; its central limit is that every chart still inherits the sampling, loss, timing and…

The Server Stopped Speaking It. The Client Still Had to Understand: RFC 2062
In December 1996, IMAP drew a line that software migrations still struggle to express. A new server could retire an old command without demanding that every client forget how to read it. RFC 2062 made compatibility directional: stop producing obsolete syntax, keep only the…

A TLS CertificateRequest Context Correlates a Response, Not an Authorization Scope
An opaque value can tell a TLS server which certificate request a client answered. It cannot tell an application what the authenticated key may do. When a correlation handle is promoted into a tenant, role or access boundary, precise cryptographic sequencing becomes an accidental…

LACNIC’s Election Upload Test Reads Bytes, Not Excel or PDF
A new compatibility test in LACNIC’s open election system carries two reassuring filenames across a disk boundary. The bytes arrive intact. That is valuable evidence—but it is evidence about transport, not about whether a workbook or a result letter is a valid document, whether…

David S. Miller and the public process behind Linux networking
A networking patch can start as a few lines of code and end up affecting servers, routers, phones, cloud hosts and appliances around the world. David S. Miller has spent decades close to the point where those changes become shared Linux infrastructure, first through the SPARC…

The Reply Was an Observation, Not Authority: RFC 2151 and the Limits of Diagnostic Tools
RFC 2151 put an Internet laboratory on an ordinary user's desk. Its commands made names, round trips, intermediate routers and remote services visible, but the very clarity of their output invited a category error: a tool could report what answered without acquiring authority to…

Dina Katabi and the Feedback Field That Was Not a Bandwidth Grant
A packet leaves its sender asking to increase the flow by a certain amount. The first router accepts the request; the second writes a smaller number; the receiver sends that surviving value back. XCP turned congestion control into an explicit negotiation, but the number in its…

Ooma's US$65m loan almost matches the cash-adjusted acquisition price
Ooma announced two cloud-communications acquisitions at headline prices that add to US$68.2 million. The final purchase-price allocations tell a different and more useful story: US$73.186 million of consideration, including US$8.563 million of cash acquired, leaves US$64.623…

Zscaler’s acquisition-adjusted growth uses three different perimeters
Zscaler reported 25% growth in both revenue and annual recurring revenue for fiscal 2026, then offered a 20% comparison that removed Red Canary. Elsewhere, its accounts valued four acquisitions and its year-end controls report excluded all four from testing. The figures are not…

SentinelOne’s Flex milestone needs a consumption bridge
SentinelOne says its Flex commercial model now accounts for more than 10% of annualised recurring revenue. That is a meaningful threshold inside a business with US$1.218 billion of ARR and US$1.7 billion of remaining performance obligations. Yet the filing also says revenue from…

SNIA sets common storage rules but cannot impose them on the market
Since 1997, SNIA has tried to make storage systems from different vendors more comparable, manageable and predictable. Its specifications cover software management, cloud data, media sanitisation, energy use and hardware form factors, but any useful rule works only when companies…

Workiva’s large-contract growth has an acquisition clock inside it
Workiva’s largest customer tiers are expanding much faster than its total customer count. That looks like a clean enterprise-upmarket story until one sentence in the filing changes the perimeter: customers acquired with Sustain.Life enter the customer count and…
