Drawing on experience building enterprise web agents, it explains why the demo succeeded and the deployment didn't, and what that means for choosing vendors, briefing the board, and avoiding mistakes others have already made. [Read on the website]() ## Issue 7 — Practitioner's Corner Lessons from the field—what we see building at scale ### Dispatches from Production Scale - [What 98% Reliability Actually Costs]() — By [Nora Kaplan]() · Published 2025-12-10 · Format: Field Dispatch When a web agent platform reports 98% success rates across thousands of sites, that number looks clean on a dashboard. Behind it sits an on-call engineer staring at authentication failures, making a judgment call. Is this our proxy network or did these sites just rotate security certificates? ### The Builders - [When Your Auditor Doesn't Have a Category for Prompt Injection]() — By [Rina Takahashi]() · Published 2025-12-10 · Format: Builder Profiles An attacker needs only your email address to hijack your ChatGPT session, replace banking details in responses, extract data from Copilot. You never opened the malicious email. The attack happened anyway. Some vendors patched it. Others called it intended functionality. ### The Number That Matters - [False Failures: Anywhere From 0% to 100%]() — Published 2025-12-10 When your automated tests fail, how many failures are real? Anywhere from none to all of them. ### Field Notes from the Ecosystem Cloudflare went down twice in three weeks. Both times from routine config changes. The second outage happened because the fixes from the first one weren't deployed yet. That's infrastructure in December. Enterprises keep discovering gaps between what they're buying and what they trust. 6% fully trust AI agents with core work. 20% say their infrastructure is ready. 40% of enterprise LLM spend shifted to Anthropic this year. OpenAI called code red. API traffic now dominates the web at 80%. Rate limiters can't keep up. Here's what we're tracking. - **Same Mistake, Three Weeks Apart** — [Source]() — Published 2025-12-10 Tag: Configuration Management Cloudflare's December 5 outage affected 28% of HTTP traffic. Root cause: routine config change. Same as November 18. Safeguards identified after first incident weren't deployed yet. "Would have helped prevent today's impact but, unfortunately, we have not finished deploying them." - **Trust Gap at Six Percent** — [Source]() — Published 2025-12-10 Tag: Enterprise Adoption HBR surveyed 603 business leaders on AI agents. 6% fully trust them with core processes. 43% limit to operational tasks, 39% confine to supervised work. Security and privacy concerns dominate. Gap between spending and deployment keeps widening. - **Stability Overrides Published Schedules** — [Source]() — Published 2025-12-10 Tag: Rate Limiting Atlassian began enforcing rate limits August 2025 but reserves right to enforce earlier "where apps are highly impacting platform stability." Limits factor app identity, tenant, request volume, product edition, user count. Burst and quota periods tracked independently. - **Anthropic Takes 40% Enterprise Spend** — [Source]() — Published 2025-12-10 Tag: Market Shift Anthropic now captures 40% of enterprise LLM spend versus 24% last year, unseating OpenAI. Serves 300,000+ business customers, large accounts growing 7x. OpenAI declared "code red" December 2, pausing side projects to refocus on core experience. - **One in Five Reports Full Readiness** — [Source]() — Published 2025-12-10 Tag: Infrastructure Readiness 20% of organizations say technology infrastructure fully supports agentic AI for core processes. 15% report data and systems ready, 12% have risk controls in place. Composite index: 27% leaders, 50% followers, 24% laggards. Spending outpaces preparation. - **APIs Now 80% of Web Traffic** — [Source]() — Published 2025-12-10 Tag: API Traffic API traffic exceeds 80% of all web traffic per Akamai's State of the Internet report. 75% of API issues stem from mishandled limits. Modern APIs spanning multiple gateways create reliability problems when nodes track limits independently. ### Practitioner Resources - **How Raft Actually Works in Production Systems** — [Source]() — Published 2025-12-10 Consensus theory meets reality. Google, Netflix, Kafka implementations show what leader election costs at scale. - **Real Performance Numbers for Computer-Using Agents** — [Source]() — Published 2025-12-10 OpenAI's CUA hits 87% on navigation vs Claude's 56%. Benchmark data that matters for model selection. - **2024 Infrastructure Attack Patterns and Operational Impact** — [Source]() — Published 2025-12-10 DDoS surged 49%, major breaches at Finastra and Halliburton. Defense considerations when building automated systems. - **Where Engineering Orgs Actually Spend Resources in 2024** — [Source]() — Published 2025-12-10 ICONIQ data: 35-45% hiring AI roles, platform engineering priorities. Useful for benchmarking your own allocation decisions. ## Other sections in Issue 7 - [Daily Brief]() - [Market Pulse]() - [Foundations]() - [Echoes]() - [Vision]() ## More - [Publication guide]() - [Issue archive]()
