Amazon S3 Tables now offer managed migration of Apache Hive tables to Apache Iceberg

Today, we’re announcing a simple, cost-effective path for data lake modernization. Amazon S3 Tables now support managed migration of your Apache Hive tables to Apache Iceberg . Migration works with Parquet tables in Amazon S3 that are registered in the AWS Glue Data Catalog and allows you to upgrade your data lake with no pipelines to build or compute to provision, while produc

Predicting and detecting failures: How Azure strengthens reliability for mission-critical workloads

Takeaway : Azure Failure Prediction and Detection (AFPD) is Microsoft Azure’s end-to-end system aiming to catch hardware failures before they interrupt a workload, not after. Across the Azure fleet, AFPD has improved the prevention of hardware-related VM interruptions by 36% . SAP workloads offer a compelling example of AFPD’s value, illustrating why preventing interruptions ma

See the agents, set the terms: new visibility and control for personal agents

Personal agents are the intermediary between humans and the Internet, turning a person’s instructions into requests and actions on websites. A customer might ask a personal agent to compare products across your site, find support articles, or complete a purchase. To a site owner, all three interactions show up as automated traffic — and without a clear view of which agents are

Introducing Zero Wire, a hub for investigating critical Internet vulnerabilities

You run security at your organization. It’s 7:00 am, and you’re having breakfast. You receive a ping: a new critical vulnerability has been disclosed. Your team scrambles to compare vendor advisories, read technical research, check which systems run the affected software, and answer familiar questions from the business: are we affected, and what are we doing about it?

AWS Weekly Roundup: GPT-6.1 Terra on Bedrock, Step Functions as agent tools, and more (November 2, 2026)

The agentic launches that stayed with me last week had nothing to do with how capable a model is. They were about reach. AWS Step Functions , which already orchestrates over 220 AWS services, can now be handed to an agent as a tool, so workflows teams already trust became callable without a rewrite. In the same week, the AI blog published how one engagement platform exposed rou

How we halved DNS build delay and cut memory use by 85%

When I last wrote about our DNS propagation pipeline in 2022 , the Zone Builder received about 250 DNS record changes per second. Today it receives about 700, nearly three times as many, plus about 100 other events, such as zone setting changes. However, the number of events was never the real problem. The problem was the kind of work some of those events needed, and how that w

4 real? Tracking exploitation and patching of eMudhra’s weak keys

On October 19, 2026, we learned about eMudhra’s eight shockingly weak keys: where eMudhra was trusted to pick a 115-digit number for their virtual combination lock protecting the Internet, they picked the number 4. Not even four digits, just the number 4. The other seven keys were similarly weak: 56, 66, 115, 155, 156, 230 and 237. The next day, we wrote a blog post on the imme

Cloudflare services for private origins is now generally available

Today, Cloudflare services for private origins is generally available. Point a proxied DNS record at a private IP, and Cloudflare reaches the origin over your existing Cloudflare One connection . Your origin stays private, while web application firewall ( WAF ), caching , bot management , and Workers work just as they do for public origins. In June, we launched this capability

Introducing the Microsoft Copilot harness in Foundry Agent Service

A model can reason about a task. Completing that task takes more: the right context, tools, execution environment, and controls, and an agent loop that brings them together. Microsoft’s unified harness strategy brings a shared execution foundation across our agent experiences while preserving customer choice. In Microsoft Foundry, that means you can choose a supported model and

Scale reservoir uncertainty analysis with agile reservoir modeling

Turn subsurface uncertainty into decision-ready insight Drilling campaigns are among the most expensive and operationally complex activities in the energy industry. Rigs, crews, equipment, and logistics are scheduled months in advance, leaving little room for delay. Every hour of downtime can carry significant costs.

What took the Internet offline in Q3 2026

The Internet can feel invisible when everything is working normally. But when connectivity breaks, the many systems it depends upon become evident in an instant. Because Cloudflare’s global network handles more than 20% of the web’s traffic, it offers a unique perspective of how Internet traffic is behaving. When failures in infrastructure, power, policy, or security disrupt ac

Introducing the Cloudflare PHP Capture the Flag challenge

Last week was one for the Internet security history books. First, eight eMudhra intermediate certificates were compromised , creating the possibility of forged certificates that could be used to impersonate servers. Then came php2shell : serious vulnerabilities in PHP, the runtime behind a large portion of the Web. Cloudflare worked around the clock as these events unfolded to

Cross-request KV cache exposure in the GLM-5.3 Workers AI model, and our remediation with SGLang

On September 8, 2026, we were alerted by a security researcher, Gadi Evron from Knostic, to a tenant isolation issue affecting the GLM-5.3 Workers AI model ( @cf/zai-org/glm-5.3 ) starting on August 27, 2026. We have remediated the issue, and we restored the model on September 9. We have confirmed that no other model hosted on Workers AI was affected. Between August 27 and Sept

Origin Range Requests: Serving large files without range-request tuning

A video player seeking to the middle of a movie asks for a few megabytes. Under our old range caching, that one request could make Cloudflare pull 128 MiB from the origin and move it between data centers, sometimes after the viewer had already left. Range requests are how large files get delivered, and caching them naively easily leads to wasted network bandwidth and wasted dis
