outage

Coinbase CEO Brian Armstrong posted on the X platform that there was a service outage at Coinbase yesterday, which is absolutely unacceptable. The root cause was multiple cooling units at the AWS data center failing simultaneously, leading to overheating in one server room. Most of Coinbase's systems are designed with redundancy to handle the failure of a single availability zone, and they did operate normally last night.However, centralized exchanges were not spared, as their architecture is specially optimized for low latency and customer co-location, making it difficult to simultaneously ensure fault tolerance at the availability zone level. While enabling the exchange to withstand availability zone failures would introduce latency issues and disrupt customer co-location, the team will reassess these trade-offs to at least ensure that when a switch to a different availability zone is needed, the duration of the outage can be significantly reduced. He expressed gratitude to the AWS and Coinbase teams who worked through the night to repair the issue and promised to release a detailed technical explanation later.

Coinbase stated that the system detected a high error rate in multiple services, subsequently pinpointing the failure to the AWS US-EAST-1 availability zone use1-az4. The Coinbase system originally had single availability zone fault tolerance, but this failure affected multiple availability zones, resulting in a prolonged interruption of core trading services.The main issues have now been fully resolved, and the team will conduct a comprehensive analysis of this incident and provide further updates after AWS releases the official review report.

As the Ugandan government cut off nationwide internet access during the presidential elections, the encrypted communication app Bitchat became one of the most downloaded apps locally. The Uganda Communications Commission confirmed that the internet shutdown took effect at 6 PM local time on Tuesday and will continue throughout the election period.Reports indicate that Bitchat relies on Bluetooth Mesh networks to enable encrypted communication without the internet, and it has simultaneously topped the download charts on both the Apple App Store and Google Play in Uganda. Meanwhile, several VPN apps also ranked high in downloads, indicating a significant increase in local demand for information access ahead of the elections.The Ugandan government stated that the internet shutdown aims to prevent the spread of false information during the elections, but opponents argue that this move could restrict the flow of election-related information. The executive director of the Uganda Communications Commission had previously stated that there would be no internet shutdown, but ultimately, the measures were implemented. As of early January, it has been disclosed that over 400,000 users in Uganda have downloaded Bitchat.This marks the third consecutive time Uganda has implemented a nationwide internet shutdown during presidential elections. Similar actions occurred during the elections in 2016 and 2021. Reports also mention that Bitchat has been widely used in various countries under conditions of internet restrictions or sudden disasters in recent years, gradually becoming an alternative communication tool in offline environments.

The Ethereum L2 network Starknet released an analysis report on the short-term mainnet outage that occurred this Monday, stating that the cause of the incident was the inconsistency between the execution layer (blockifier) and the proof layer: under specific cross-function calls and rollback combinations, the execution layer incorrectly recorded a state write that had been rolled back, leading to abnormal transaction execution. The related transactions did not receive L1 finality confirmation. This incident triggered a block reorganization, with approximately 18 minutes of on-chain activity being rolled back.This is the second major interruption since 2025, following a September incident where a sequencer vulnerability caused an outage of over 5 hours and rolled back about 1 hour of on-chain activity.

CyrusOne confirmed that its data center in Aurora, Illinois, experienced a market outage operated by the CME Group for over 10 hours due to human error.On-site staff and contractors failed to drain the cooling towers according to standard procedures before the arrival of low temperatures, ultimately leading to an overload of the cooling system and a rise in temperature. CyrusOne is jointly owned by KKR & Co. and Global Infrastructure Partners, and this incident has raised concerns about the reliability of financial market infrastructure. Previously, on November 28, trading in commodity futures at the CME Group was suspended.

Due to a Cloudflare service outage, both OpenSea and Upbit websites are experiencing downtime, showing a "500 Internal Server Error" message.

According to an analysis report published by Cloudflare's official blog, the large-scale outage on November 18 was not caused by an external network attack, but rather by an erroneous configuration file generated after a database permission adjustment, which led to anomalies in the core proxy system. This triggered interruptions in multiple products, including CDN, security services, Workers KV, Turnstile, and Access, marking the most severe incident since 2019.The report noted that in the early stages of the incident, the team mistakenly assessed it as a DDoS attack, and ultimately completed the fix by rolling back to an old configuration file. The related services were fully restored at 01:06 AM Beijing time on November 19. Cloudflare described this outage as "unacceptable" and will accelerate the improvement of system resilience.

ChainCatcher message, Conduit released a post-mortem analysis report regarding the previous downtime incident of Degen Chain. On May 10, Conduit increased the batch size for Degen and Proof of Play Apex to 10MB to reduce costs, which delayed the time for data to be batch published from these networks to their parent chain. On May 12, this configuration was reverted to fix the batch publishing. This led to reorganizations on both networks, as the batch was published after a 24-hour forced inclusion window. Arbitrum Nitro will insert any inbox messages before any transactions in the batch and replay those transactions using the new timestamps.After the reorganization, nodes returned with corrupted databases due to their depth not being well handled by geth. This required resynchronizing the data directory from genesis. The synchronization time for each network exceeded 40 hours, with a replay rate of about 100M gas/s. Once the nodes were resynchronized, Conduit attempted various transaction replay strategies, although not all transactions could be recovered, as some relied on precise timestamps.After negotiating with each rollup team, Conduit discussed and concurrently tried various strategies to bring the network online and restore the state prior to the reorganization. The Degen Chain network was restored online 54 hours after the outage. The Apex chain of Proof of Play was restored around the same time but became available to the public only after implementing another recovery solution.Conduit stated that it has improved alerts and monitoring for the Orbit chain to cover such situations and is committed to working with Offchain Labs to enhance the observability of all Orbit chain operators. The team will continue to invest in and research mechanisms to better simulate mainnet conditions and transaction payloads in a testing environment. The Degen Chain Explorer is now displaying the latest status of Degen Chain normally.
