Migrating data ingestion systems that process petabytes of social graph data every single day comes with zero room for error, especially when the migration has to happen live, under production traffic.
We recently completed a 100% migration to a new hyperscale data warehouse service with zero downtime. To seamlessly transition tens of thousands of incremental ingestion jobs at scale, our teams designed the clear migration job lifecycle and built automated tooling to effectively manage the multi-phased rollout.

We’re rolling out version 1.1 of Labyrinth, the encrypted storage system and protocol that secures messages and history on Messenger.
Labyrinth 1.1 enhances the reliability of end-to-end encrypted backups with a new sub-protocol that helps messages survive the loss of a device, a switched device, and long gaps between sign-ins.
Read our updated white paper, “The Labyrinth Encrypted Message Storage Protocol” for more details: https://t.co/RO5G5RSZ7f
We're sharing a deep dive into how we're hardening end-to-end encrypted backups for WhatsApp and Messenger:
• HSM-based Backup Key Vault stores recovery codes in tamper-resistant hardware
• Over-the-air key distribution decouples infrastructure rotation from app releases
• Cloudflare-signed attestation bundles provide independent verification
• Public deployment evidence for every new HSM fleet

We're breaking ground on a new AI-optimized data center in Tulsa, Oklahoma.
A few things that make this facility interesting from an engineering perspective:
💧 Cooling: Closed-loop, liquid-cooled system that recirculates the same water + uses zero water for server cooling during the majority of the year.
⚡ Energy: 100% clean energy match. We're adding over 1,500 MW of clean energy to the grid in Oklahoma, and paying hundreds of millions through utility bills to fund grid infrastructure like substations + transmission lines.
🎓 Workforce pipeline: Partnering with Tulsa Tech + Tulsa Community College on a new cross-institutional program for digital infrastructure careers, targeting 200+ graduates annually in cooling simulation, fiber optics, structured cabling + AI/data analytics.
🌾 Water restoration: A 10-year partnership with Phytech to deploy plant-sensor technology across ~1,500 acres of commodity crops near Tulsa, saving 50M+ gallons of water per year.

Today we're announcing LevelUp: a free, four-week training program that takes people with no prior experience and prepares them to work as fiber technicians on data center construction sites across the US.
We built this program with CBRE because the fiber technician field, and the broader construction industry, is facing a nationwide shortage at a time when data center demand is higher than ever.
How it works:
🔧 Classroom instruction, hands-on labs + team activities covering transferable technical skills
🎓 Graduates have the opportunity to work at Meta's US construction sites through our contractor network
🤝 Open to everyone from recent high school grads to mid-career professionals
Since 2010, Meta's data center projects have supported 30,000+ skilled trade jobs during construction + 5,000+ permanent operational roles. LevelUp is about building the pipeline to keep that going.

As the industry transitions to post-quantum standards, we’re sharing lessons from Meta’s multi-year PQC migration.
By outlining our approach, from risk-based prioritization and building cryptographic inventories to deploying hybrid PQC-classical models, we aim to provide a roadmap for organizations strengthening their resilience against future quantum threats like "Store Now, Decrypt Later.”
We’re also proposing a framework of PQC Migration Levels (from PQ-Unaware to PQ-Enabled) to help teams manage complexity across diverse use cases.

At Meta, WebRTC powers real-time audio and video across 50+ use cases. But forking a large open-source project within a monorepo presents a unique challenge — over time, an internal fork can drift behind upstream, cutting itself off from community upgrades.
We built a dual-stack architecture that enabled safe A/B testing across all 50+ use cases, then built workflows that keep us continuously upgraded with upstream, improving performance, binary size, and security across the board.
Here's how we escaped the "forking trap" ↓

We're open-sourcing BOxCrete, a new AI model for the construction industry.
Using Bayesian optimization, BOxCrete helps producers rapidly design concrete mixes with domestic materials, bypassing months of lab work.
The results from our data center build in Rosemount, MN:
🚀 43% faster time to full structural strength
🛠️ 10% reduction in cracking risk
🇺🇸 100% domestic material usage
We are open-sourcing the model and the foundational data to empower producers everywhere. Check out the full technical deep dive on our Engineering blog: https://t.co/voV8yMLZFa
Our next-gen data center in El Paso, Texas is officially growing to 1GW. Here are a few updates:
📐 The build: We're increasing our investment from $1.5B to more than $10B, supporting 4,000+ construction jobs at peak + 300 permanent operational roles once complete.
🎓 The community: A new $500K workforce development partnership with El Paso Public Schools will connect students with career paths in STEM + trades through real-world learning experiences.
💧 Water stewardship: The data center's closed-loop cooling system means zero operational water use most of the year. We're also partnering with @DigDeepH2O to bring clean water to 100+ homes for the first time and Bonneville Environmental Foundation to restore millions of gallons annually through new irrigation tech for local farmers.
