### AI overview

A decade of DNS measurements across the Tranco top 1 million domains shows that email infrastructure is consolidating around Google Workspace and Microsoft 365. Self-hosted mail servers declined from 44.6% in 2016 to 22.4% in July 2026, while the two leading providers together handled 38.6% of measured domains. DMARC enforcement has plateaued, and a large long tail of infrastructure remains difficult to classify. The article frames this concentration as a resilience concern because outages, filtering changes, or policy decisions could affect a substantial part of the email ecosystem.

### Source excerpt

Ten years of DNS measurements reveal three trends across the Internet's most popular domains: email continues to consolidate around two providers, DMARC enforcement has hit a plateau, and a surprisingly large long tail of infrastructure defies easy classification.

### AI overview

This article describes how a Microsoft procurement professional built the Supplier Price Interpreter with M365 Chat Agent Builder. The agent uses supplier price sheets stored in a structured Teams channel as a knowledge source and responds to plain-language prompts about the data, aiming to reduce manual comparison work in RFP and RFx processes.

### Source excerpt

Image generated by AI Picture this: It's late in the week, an urgent sourcing decision is due, and sitting in your inbox are three separate supplier price sheets -- each formatted differently, each with its own tab structure, its own naming conventions, its own quirks. Your job is to compare them, find the gaps, flag the inconsistencies, and deliver a recommendation. The clock is ticking. This isn't a hypothetical scenario. It happens regularly in procurement teams running large scale RFP and RFx processes. For years, the solution was straightforward: Open each file and compare them line by line. It worked, but it was slow, manual, and far removed from the strategic work that sourcing professionals are hired to do. In a world where business decisions move fast and supplier negotiations are time-sensitive, delays in price review have real consequences. Slower cycles, missed windows, and sourcing teams spending their cognitive energy on extraction instead of analysis. So, we asked the question: What if the extraction part could just happen on its own? Starting small, at the desk The Supplier Price Interpreter didn't start as a grand initiative. It started as a practical frustration. Rupa Shastri, a procurement professional within Microsoft's broader procurement organization, built the agent right at her desk using M365 Chat Agent Builder. No dedicated engineering team, no lengthy development cycle, no new infrastructure. Just a clear problem, an available tool, and the willingness to try something different. Figure 1: M365 Copilot flow and the actionable insights it provides. Working within a large enterprise procurement environment, where supplier bids come in across multiple RFx engagements spanning vendors, scopes, and formats, the repetitive nature of price sheet review was hard to ignore. Every engagement required the same foundational steps. Open the files, read the data, compare the numbers, find what's missing. The methodology never changed. Only the suppliers

### AI overview

EvilTokens is a phishing-as-a-service kit that abuses Microsoft 365's OAuth 2.0 device authorization flow to compromise accounts without directly stealing passwords. Victims authenticate on Microsoft's genuine login page, unknowingly approving an attacker-controlled device; the resulting access and refresh tokens can enable account takeover and business email compromise.

The article argues that keeping sensitive files on self-managed Dutch servers is not a workable safeguard if staff continue to use Microsoft 365 email and Office applications for everyday communication and documents.

### Source excerpt

Zoals ik gisteren schreef, onze maatschappij en overheden draaien in steeds grotere mate op Amerikaanse clouds, en we maken ons hier nu terecht zorgen over. Want het is toch niet leuk dat de Amerikanen mee kunnen lezen in onze (overheids)gegevens, of zonder pardon de steker eruit kunnen trekken. We zouden dit graag snel op willen lossen, maar er zijn geen makkelijke en goedkope keuzes. Inmiddels heeft (volgens geruchten) bijna de hele centrale rijksoverheid besloten om de email toch nog op eigen servers te houden, wat echt heel goed nieuws is.

A Dutch commentary highlights two personal takeaways from a 13 February 2025 Tweede Kamer roundtable on digital sovereignty in the Dutch national government. It discusses government dependence on Microsoft 365 Cloud, reliance on U.S. cloud providers for cybersecurity and service recovery, and concerns about access under U.S. surveillance law.

Het hele rondetafelgesprek van "Digitale soevereiniteit Rijksoverheid" van afgelopen 13 februari 2025 is de moeite waard. Bekijk het hier op de meer dan uitstekende Debat Direct site van de Tweede Kamer. Deelnemers Petra Oldengarm en Reijer Passchier hebben hun reflecties op de bijeenkomst al gedeeld, en ik schreef er al wat over in mijn nieuwsbrief (inschrijven kan via deze link).

### AI overview

This opinion article discusses the implications of cloud adoption for the Dutch government and organizations handling personal, medical, or criminal-justice data. It examines dependence on Microsoft 365 and Amazon Web Services, geopolitical and legal concerns about data held on US-based services, and the limited practical use of Double Key Encryption. The author argues that Europe should retain control over essential digital services and sensitive data.

### Source excerpt

Afgelopen 25 november hield ik (op persoonlijke titel) een praatje bij de Kiesraad over de toestand van de cloud, met specifieke aandacht voor de Nederlandse overheid. Iedere organisatie ziet zich nu geconfronteerd met de vrijwel verplichte gang naar de cloud. Voor een schoenenwinkel of broodjeszaak is het niet zo'n halszaak om over te gaan naar Microsoft 365 (MS365), of om afhankelijk te zijn van leveranciers die diensten leveren op basis van Amazon Web Services.

### AI overview

The article argues that nearly the entire Dutch national government, along with many municipalities and agencies, is moving workplace, document, and file management to Microsoft 365 and Microsoft's public cloud. It criticizes the concentration of government data and services with one US provider, citing legal, sovereignty, security, and outage concerns.

### Source excerpt

Eerder deze week verscheen het rapport van de Auditdienst Rijk en daar staat het helder in: het is zo "dat straks (bijna) de volledige Rijksoverheid gebruik maakt van MS 365". En voor de zekerheid, verderop staat: "Hiermee wordt de on-premises werkplek van de Rijksoverheid verplaatst naar de public cloud [van Microsoft]". Het gaat dus gebeuren, de totale migratie van onze overheid naar MS 365, op Microsoft servers in Microsoft datacenters.
