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.

The Ink team has applied a fix, and we are monitoring the results.
investigating
We are investigating an issue for safe and finalized tags on Ink Sepolia, which returning stalled block heads. The "finalized" block is currently stalled at block 50232683. This appears to be a network-wide issue affecting other providers, not isolated to Alchemy. We are monitoring for updates from the Ink team and will provide further information as it becomes available.
We are currently investigating degraded performance on Ethereum Sepolia. Block production has been intermittent, with the chain's head advancing unevenly.
This appears to be a network-wide issue. Alchemy's infrastructure is operating normally and we do not currently anticipate customer-facing impact.
We will continue to monitor and provide updates as we learn more.
We're currently investigating a stall in finalized block updates on Ink Sepolia. The issue appears to be network-wide and is not isolated to Alchemy. We've reached out to the Ink team for additional insight and will share another update as soon as we have more information. Thanks for your patience.
