Incident History

Base Mainnet - Increased latency in EU Central region
We are observing a network-wide stall on Anime Sepolia. The chain has stopped advancing and is stuck at block 1823674, produced at 08:05 UTC, roughly 50 minutes ago. This affects all requests that depend on recent chain state, including latest block reads, new transaction confirmations, and real-time subscriptions. Historical data remains available.
This is not specific to Alchemy. Other independent providers on Anime Sepolia are returning the same stalled block, which indicates the issue originates upstream at the network level rather than within our infrastructure.
We have reached out to the network team and are monitoring block production closely. We will share an update as soon as the chain resumes advancing or we have more information. Other networks are unaffected.
Starknet Mainnet is currently not producing new blocks following a recent network-wide upgrade.
This is a chain-level condition affecting the Starknet network as a whole and is not isolated to Alchemy infrastructure.
We are actively coordinating with the Starknet team on mitigation steps and will share an update as soon as we have more information.

Several nodes in our primary fleet have successfully resynced and are now serving traffic. However, we are not yet back to full capacity; customers may experience elevated latency or an intermittent error rate. We will provide a final update once all nodes are fully back online
monitoring
Our Sonic mainnet RPC nodes are continuing to resync from the latest snapshot. During this process, all traffic is being routed through secondary infrastructure with updated binaries. Websocket connections are unavailable until the resync is complete, and customers may experience elevated latency or intermittent errors on RPC requests.
We expect the resync to finish within the next several hours and will provide another update once primary nodes are back online and operating at full capacity.
monitoring
An accidental hard fork occurred on the Sonic mainnet due to a consensus-breaking change introduced in Sonic client v2.1.6, related to an upgraded Ethereum library containing CVE security patches. Nodes running older client versions fell out of consensus at block 66,026,364, while the network itself continued producing blocks normally.
Our Sonic mainnet RPC nodes were affected. We have upgraded all nodes to v2.1.6 and initiated a full database resync from the latest snapshot. In the interim,...
