San FranciscoCoinbase posted a Q1 loss of $1.49 per share — analysts forecast $0.27 profit — while offline for hours Thursday.
Amazon Web Services’ Virginia region lost multiple availability zones simultaneously; all Coinbase trading routed through that single region.
A 14% workforce cut preceded the outage.

THE THREE-FIRM MARKET
AWS, Microsoft Azure, and Google Cloud control roughly two-thirds of global cloud infrastructure. The next tier — Alibaba, Oracle, IBM — splits most of the rest. A market that was supposed to commoditize compute consolidated into an oligopoly tighter than the airline industry.
WHY US-EAST-1 KEEPS BREAKING
AWS's Northern Virginia region is the oldest, largest, and most heavily loaded. It hosts default endpoints for global control-plane services — IAM, Route 53, billing — meaning even customers who think they're multi-region quietly depend on it. When us-east-1 sneezes, the internet catches a cold.
THE AVAILABILITY ZONE PROMISE
Each AWS region is sliced into multiple availability zones — physically separate data centers with independent power and cooling — so workloads spread across zones survive any one failure. The promise breaks when a shared control-plane dependency or a network fabric issue takes multiple zones down at once. This is the failure mode that hit Thursday.
THE CONCENTRATION OF FAILURE
When one provider hosts a third of the internet, an outage isn't a vendor problem — it's systemic. The 2017 S3 outage took down Slack, Trello, Quora, and parts of the SEC's filing system simultaneously. Regulators in the EU and UK have begun classifying hyperscalers as critical infrastructure for exactly this reason.
WHY EXCHANGES PICK ONE REGION
Crypto exchanges co-locate matching engines in a single region to minimize latency between order book, risk engine, and database. Replicating across regions adds milliseconds that arbitrageurs exploit. The same logic that makes a single region fast makes it a single point of failure — the tradeoff every exchange makes and most users never see.
THE LAYOFF SIGNAL
Coinbase's 14% cut before the outage fits a pattern: workforce reductions in cloud-native firms often hit site reliability and platform teams hardest because their work is invisible until it isn't. The 2022 Twitter cuts and the 2023 Meta layoffs both correlated with subsequent infrastructure incidents the firms had previously avoided.
