Brian Armstrong: Architecture will be reassessed, and future downtime should be significantly reduced

Odaily Planet Daily reported that Coinbase CEO Brian Armstrong stated on platform X that Coinbase experienced a downtime last night, the root cause being multiple coolers malfunctioning in the AWS data center, leading to overheating in the server room. Most systems are designed to be redundant and operate normally in the event of a single AWS availability zone failure, but centralized exchanges, optimized for low latency and customer colocation, were unable to achieve this redundancy. While it is possible to make the exchange resilient to availability zone failures, doing so would introduce latency and disrupt customer colocation.

In light of this incident, these trade-offs will be reassessed. At the very least, when it becomes necessary to migrate availability zones, the downtime should be significantly reduced. Armstrong thanked the AWS and Coinbase teams for working through the night to mitigate the issue, and stated that a detailed technical summary will be shared later.
