Several major crypto exchanges, including Binance, KuCoin, and MEXC, experienced temporary disruptions after a connectivity issue hit Amazon Web Services' Tokyo region earlier today. The interruptions triggered brief withdrawal suspensions and user-facing issues across multiple platforms.
Background
- In the early hours of Tuesday, a connectivity glitch at Amazon Web Services’ (AWS) Tokyo data center disrupted operations for several crypto platforms relying on AWS cloud infrastructure.
- Binance, the world's largest crypto exchange, temporarily halted user withdrawals “to keep safe,” citing backend service issues tied to the AWS outage.
- The issue, first identified by AWS at 1:15 a.m. PDT, was fully resolved by 1:51 a.m. PDT according to AWS’ service status dashboard.
- Binance resumed withdrawals within 23 minutes and confirmed the matter had been addressed swiftly.
- Kucoin also later reported restoration of services. However, other platforms weren’t as quick to bounce back. MEXCreported lingering service irregularities and announced compensation measures for impacted users.

Why Should You Pay Attention?
- The incident highlights the growing dependency of digital asset platforms on centralized cloud infrastructure.
- While no user funds were reported lost, the event pointed out the systemic risks tied to cloud service centralization.
- Disruptions like these can hinder market activity, distort price feeds, and affect user trust in platform reliability—especially during periods of heightened market volatility.
Who Said What?
- Binance (via X):
“All services are starting to recover and resume. Withdrawals have also reopened. Please note that some services might experience delays while the system fully recovers.”
- KuCoin (via X):
“All services have now been fully restored and trading operations are functioning normally. We sincerely apologize for the inconvenience caused by this unexpected disruption and deeply appreciate your patience and understanding during this time.”
- KuCoin Spokesperson:
“Some services have already been restored… No user assets or data have been affected.”
- MEXC (via X):
“Due to a service disruption with AWS, some users may currently experience issues on the MEXC App and Web platform, including abnormal candlestick charts, failed order cancellations, and delays in spot asset transfers.”
- AWS Spokesperson:
“The issue has been resolved and the service is operating normally.”
Zooming Out
- This AWS outage is the latest reminder of how centralized infrastructure (even in a decentralized financial ecosystem) can create single points of failure.
- As more crypto platforms scale globally, reliance on services like AWS for backend infrastructure remains a key vulnerability.
- While responses from exchanges were swift, the event adds to a growing conversation about redundancy, failover strategies, and whether decentralized hosting solutions will become necessary to ensure uninterrupted service in a maturing Web3 environment.
