AI Daily Brief — 20 October 2025

Monday landed four landmark stories. The AWS US-EAST-1 outage ran from Oct 19 11:48 PM PDT through Oct 20 ~2:20 PM PDT — root cause a DNS Enactor race condition that produced an empty DNS record for the DynamoDB endpoint; DNS restored by 5:24 AM ET but the fix exposed cascading EC2 + NLB health-check failures. Hit 140+ AWS services + 1,000+ downstream apps: Snapchat, Fortnite, Roblox, Coinbase, Venmo, Duolingo, Disney+, Prime Video, Ring, Alexa, Slack, Atlassian, Canva, Signal, Pokemon GO, Delta, Uber, Starbucks, UK HMRC. Perplexity CEO Aravind Srinivas publicly confirmed Perplexity was taken down. ~6.5M Downdetector reports globally. OpenAI + SAG-AFTRA + Bryan Cranston + UTA + CAA + ATA issued a joint statement: Sora 2 will use opt-in policy for voice/likeness, with strengthened guardrails for non-opted-in figures plus support for the NO FAKES Act. DeepSeek open-sourced DeepSeek-OCR — 3B VLM (DeepEncoder + DeepSeek3B-MoE-A570M decoder) compressing long text into vision tokens at ~97% OCR precision at <10× compression, 200,000+ pages/day on a single A100. Judge Stein (SDNY) denied OpenAI’s motion to dismiss output-based copyright claims in the multi-district class action by authors including George R.R. Martin — outputs could be “substantially similar” to plaintiffs’ works.

Top stories

  • AWS US-EAST-1 ~15-hour outage. DynamoDB DNS race condition (DNS Planner + DNS Enactor); empty DNS record for dynamodb.us-east-1.amazonaws.com; ~37 min to identify, fix at 5:24 AM ET, but cascading EC2 + NLB health-check failures extended impact. AWS disabled DynamoDB DNS Planner + Enactor worldwide pending fix. via The Register

  • Perplexity offline — CEO confirms AWS root cause. Aravind Srinivas publicly attributed the disruption to AWS US-EAST-1 issues. via BleepingComputer
  • OpenAI + SAG-AFTRA + Bryan Cranston joint statement. Sora 2 to use opt-in policy for any voice/likeness depiction; strengthened guardrails for non-opted-in figures; support for NO FAKES Act. UTA, CAA, ATA also signatories. Followed unauthorized Cranston + Michael Jackson + Ronald McDonald clips. via SAG-AFTRA
  • “Dead celebrity loophole” remains. Prohibition extends only to living public figures — Tupac, Marilyn Monroe, Queen Elizabeth II still in user-generated videos. MLK Jr content blocked at estate’s request prior week. via CNBC
  • DeepSeek-OCR open-sourced. 3B VLM (DeepEncoder + DeepSeek3B-MoE-A570M decoder) compressing long text into vision tokens. ~97% OCR precision at <10× compression, 200K+ pages/day single A100. Weights on GitHub + Hugging Face; arXiv 2510.18234. via DeepSeek / GitHub
  • DeepSeek-OCR confirmed on DGX Spark. Simon Willison ran the weights on an NVIDIA DGX Spark via Claude Code Oct 20 — independent confirmation of the same-day release. via Hugging Face
  • Judge Stein denies OpenAI motion to dismiss. SDNY denied OpenAI’s motion in consolidated MDL class action by authors including George R.R. Martin — outputs could be “substantially similar” to plaintiffs’ works. Core copyright case advances toward summary judgment. via IPWatchdog
  • CoreWeave + Poolside on 40K+ NVIDIA GB300 NVL72 cluster. Partnership delivers state-of-the-art GB300 NVL72 cluster >40K GPUs to Poolside’s 2GW Project Horizon AI campus in West Texas. via CoreWeave
  • OpenEvidence raises $200M at $6B. Medical-AI search (“ChatGPT for doctors”) — round led by GV with Sequoia, Kleiner Perkins, Blackstone, Thrive, Coatue, BOND, Craft. Doubled July valuation. Monthly clinical consultations near-doubled to 15M since July. via TechCrunch

Who shipped

DeepSeek shipped DeepSeek-OCR. OpenAI shipped the SAG-AFTRA agreement. CoreWeave + Poolside announced 40K GB300 partnership. OpenEvidence closed Series. AWS shipped a 15-hour outage and a still-rolling post-mortem.

Open-source pulse

DeepSeek-OCR is the day’s open-source story — context optical compression for long text, 3B params, MIT-license-compatible. Independent verification by Willison on DGX Spark within hours of release. China dominance continues.

Money, infra & hardware

The AWS outage reignited the cloud-concentration-risk regulatory debate — EU classifies AWS/Google/Microsoft among 19 “critical ICT providers,” UK FCA + European Banking Authority treat major cloud providers as critical third parties. CoreWeave-Poolside 40K GB300 + 2GW campus is the day’s structural compute commitment. OpenEvidence $6B is the day’s frontier health-AI valuation.

Quiet corners

The Stein ruling is the major copyright story of the day — first time output-based ChatGPT claims survive an OpenAI motion to dismiss. Core case proceeds toward summary judgment with discovery and substantive briefing.
