MOD-01 // POST-MORTEMS
Root-cause timelines of verified OpenAI, Anthropic, Cloudflare, and GitHub incidents, detailing how multi-step tool-calling agents stall under HTTP 429, 503, and 529 responses.
AI Infrastructure Outage Telemetry, Compound SLA Cascade & Agent Failover Bench
Single-turn chat tolerates brief API jitter; 8-hop autonomous tool loops multiply every upstream blip. Monitor 5-minute polled Statuspage v2 feeds and model serial availability erosion side by side below.

Data source & lag notice: Rows poll every 5 minutes from each provider's public Statuspage v2 JSON endpoint and may lag behind live HTTP 429/5xx bursts. Plain-text names identify services without logos or endorsement. Unreachable feeds map strictly to Unknown, never Operational.
Compound SLA Cascade Visualizer
Unhedged multi-agent tool chains fail whenever any serial dependency drops (R = p^n). Adjust hop depth to inspect availability decay.

Why Status Green Still Drops Multi-Agent Runs
Public status pages reflect broad regional incidents, whereas autonomous loops break on localized tail-latency spikes, HTTP 529 capacity shedding, and unhedged tool retries. Pair external status polling with per-hop circuit breakers.
Hardware & Failover Incident Dossier
Architectural failure modes extracted from primary OpenAI, Cloudflare, Anthropic, and GitHub post-mortems, paired with our four reliability engineering references.
Inference Compute Saturation
HTTP 529 / 429Separate overloaded gateway codes (529) from org rate limits (429); trip cross-provider fallback within a 4s TTFT deadline.
Control-Plane vs Data-Plane Coupling
DNS & KV STATENever block per-turn agent orchestration on synchronous control-plane KV writes; buffer state in local durable queues.
Post-Recovery Duplicate Side Effects
WEBHOOK REPLAYAttach SHA-256 deterministic idempotency keys (runId + step + canonical args) so delayed webhook replays never double-commit.
MOD-02 // SLA MATH
Model compound availability (R = p^n) across 1 to 15 sequential LLM, vector DB, and MCP tool hops, and quantify how secondary-provider circuit breakers cut monthly downtime.
MOD-03 // FAILOVER RPC
Reference TypeScript and infrastructure patterns for 4-second Time-to-First-Token budgets, cross-provider model fallback, and deterministic tool-call idempotency keys.
MOD-04 // CONTAINMENT
SRE outage-containment patterns: prompt-taint separation, short-lived OAuth On-Behalf-Of (OBO) credentials, and Firecracker / gVisor / Wasmtime workload isolation.
