cloud storage

A cross-tenant data exposure flaw in Cloudflare's Containers and Sandboxes has been disclosed and fixed. The issue stemmed from dm-thin storage pools running with skip_block_zeroing enabled, meaning newly written 4 KiB pages into unmapped 64 KiB blocks could leave residual data on raw devices. A Workers Paid tenant could reportedly read up to 60 KiB of data left behind by a previous tenant from /dev/vdc. Cloudflare has patched the issue, and security communities are discussing the implications of shared-storage isolation failures in multi-tenant cloud platforms.

Backblaze has published its quarterly drive reliability report covering the second quarter of 2026, detailing annualized failure rates across the hard drives in its cloud storage fleet. The report is a regular fixture for anyone tracking which drive models hold up best over time, and the latest edition drew a large, engaged audience on Hacker News as readers compared model reliability and annualized failure figures.

A question raised in the developer community asks whether AI agents should be allowed to access cloud files under least-privilege permissions. The discussion touches on how to scope agent access to storage safely, and what safeguards are needed to prevent overreach. Commenters are weighing security trade-offs of letting automated agents read and write cloud documents.

A discussion of orbital data centers — the idea of shifting cloud computing infrastructure into space — is drawing attention. The concept, promoted by space industry players and examined by bodies like the ITU, would place compute and storage on satellites powered by uninterrupted solar energy, easing terrestrial energy demands. Supporters see a route around data center power and cooling limits; skeptics point to launch costs, radiation, and maintenance challenges.

A technology educator has shared a walkthrough of the main components found inside a data center rack, explaining what each part does. The breakdown covers standard hardware such as servers, switches, storage and power distribution, and is aimed at readers wanting a plain-language primer on data center infrastructure. It is being shared alongside free downloadable infographics and ebooks on computing topics, drawing attention from people interested in hardware and IT basics.

A cybersecurity writer is promoting a layered privacy setup for 2026 that combines encrypted email, a no-logs VPN, DNS filtering and encrypted cloud storage. The idea is that each layer covers for the others, so no single leak exposes a user's data. The guide is circulating among privacy and infosec audiences.
