Yandex outage: Data shows that instead of going dark, malicious bots went on the move
Cloudflare uses Radar and Bot Management data to show that after reported strikes on Yandex data centers, the traffic drop from Yandex Search was mostly verified crawlers, while malicious automation on Yandex.Cloud largely migrated to other hosting providers, a reminder that ASN traffic volume is a poor proxy for bot behavior.

The people holding up the internet
A sheets.works data story that counts who actually maintains 23 pieces of software every phone, browser and server depends on. It finds 11 of 23 projects rely on one or two regular contributors, and tells the stories of maintainers such as Paul Eggert (time zone database), Lasse Collin (xz), Denis Pushkarev (core-js), Todd Miller (sudo) and the SQLite, zlib, bash and curl teams.

Jev-Driven SRE Diagnosis: What Worked and What Failed
The SREGym team builds a Kubernetes incident-diagnosis pipeline with no LLM agent: a programmatic collector gathers cluster evidence and TypeSafe AI's Jev decision model picks root-cause candidates and supporting evidence. It passed 80 of 105 diagnoses (76.2%) across 21 SREGym-Lite faults with a 14.6s median, close to an LLM agent's score at far lower cost, and the post dissects the faults it failed.

Among European Companies That Use a CDN, Nearly 9 in 10 Use Cloudflare
An analysis of 44,143 European companies that use a CDN found that 89.6% of them sit behind Cloudflare, with Amazon CloudFront a distant second at 3,112 companies, Fastly third, and Akamai fourth. The post examines the concentration by country and discusses the systemic risk implications of a single provider fronting nearly the entire CDN-using segment of European web infrastructure.
