An outage at an AWS data centre impacted crypto exchanges like Binance and KuCoin. The issue was resolved swiftly due to an interruption in power to certain EC2 instances. Binance reported that services were recovering, though some delays might persist. AWS plans significant investment in cloud infrastructure in Japan to enhance service reliability.
An outage at an Amazon Web Services (AWS) data centre has disrupted operations for several cryptocurrency exchanges, including Binance and KuCoin. Binance confirmed via a post on X that the issue stemmed from a “temporary network interruption” affecting their services.
The AWS Health Dashboard later reported that the connectivity problems involved a subset of EC2 instances within a specific Availability Zone (apne1-as4) located in the AP-Northeast-1 region. This issue was linked to a disruption of both primary and secondary power supply to the concerned EC2 instances, leading to increased error rates and latencies across services powered by these instances.
AWS engineers were engaged quickly to examine potential mitigations, and the issue was resolved without expectation of recurrence. Binance noted progress in recovering services, although some users may still face delays; the exchange managed to reactivate withdrawals merely five minutes post-outage notification.
The AP-Northeast-1 region, situated in Tokyo, Japan, encompasses four availability zones. AWS announced intentions to invest over $15 billion into enhancing its cloud infrastructure in Japan by 2027, aiming to bolster data centres in Tokyo and Osaka. AWS established a presence in Japan in 2009, introducing its first cloud region in 2011 and another in Osaka in 2021.
This is not AWS’s first encounter with outages in Tokyo; the region faced a six-hour outage in 2021 due to complications with the AWS Direct Connect hybrid cloud networking service. Issues with multiple network devices were the primary cause of that disruption.
