To Beat Neocloud Rivals To OpenAI, CoreWeave Spends Like Crazy
Sometimes, when datacenter computing does a paradigm shift, things get cheaper, like the move to RISC/Unix systems in the 1990s, and then to X86 systems in the 2000s. …

HN792: Understanding Agentic AI for Network Operations (Sponsored)
LLMs and AI-powered chatbots are becoming a regular feature of network operations tools and vendor product portfolios. Now the next iteration of AI in network ops and automation is likely to be agentic. On today’s Heavy Networking, sponsored by HPE Juniper Networking, we talk about what agentic AI actually means, how AI agents will accomplish... Read more »Congestion Control at IETF 123
As usual, IETF 123 was a busy week for DNS folk. I'll cover the material presented at the DELEG and DNSOP working groups. There is more to the DNS at IETF meetings than just these two working groups, and I'll skip over Adaptive DNS Discovery (ADD), Extensions for Scalable DNS Service Discovery (DNSSD), and DANE Authentication for Network Clients Everywhere (DANCE) in the interests of trying to keep this report (relatively) brief!Congestion Control at IETF 123
The Internet Engineering Task Force (IETF) meets three times a year to develop Internet Standards and related best practices. At its July 2025 meeting in Madrid, several sessions explored the evolving role of congestion control in transport protocols and sparked the observations in this post.Congestion Control at IETF 123

MadeYouReset: An HTTP/2 vulnerability thwarted by Rapid Reset mitigations
On August 13, security researchers at Tel Aviv University disclosed a new HTTP/2 denial-of-service (DoS) vulnerability that they are calling MadeYouReset (CVE-2025-8671). This vulnerability exists in a limited number of unpatched HTTP/2 server implementations that do not sufficiently enforce restrictions on the number of times a client may send malformed frames. If you’re using Cloudflare for HTTP DDoS mitigation, you’re already protected from MadeYouReset.
Cloudflare was informed of this vulnerability in May through a coordinated disclosure process, and we were able to confirm that our systems were not susceptible, due in large part to the mitigations we put in place during Rapid Reset (CVE-2023-44487). MadeYouReset and Rapid Reset are two conceptually similar HTTP/2 protocol attacks that exploit a fundamental feature within the HTTP/2 specification: stream resets. In the HTTP/2 protocol, a "stream" represents an independent series of HTTP request/response pairs exchanged between the client and server within an HTTP/2 connection. The stream reset feature is intended to allow a client to initiate an HTTP request and subsequently cancel it before the server has delivered its response.
The vulnerability exploited by both MadeYouReset and Rapid Reset lies in the potential for malicious actors to abuse this Continue reading
