Consensus Issues on Ropsten
Incident Report for Infura
We've completed the transition of all facets of our Ropsten infrastructure to the new chain and will continue to monitor the network for stability. Any user that sent transactions between blocks 10679538 and 10688318 on the old chain are encouraged to double check that they are still mined on the new chain.

We are continuing to update our Ropsten infrastructure to the the new consensus chain. As we migrate portions of our infrastructure to the new chain users can expect to see inconsistent results, especially between logs/events and block contents. As such users are further encouraged to avoid using Ropsten until this process is complete.

We are beginning the process of upgrading our Ropsten nodes to resolve the consensus issue raised yesterday. This will require rolling back our Ropsten network state to before the invalid block, leading to a very large network reorg. As such users should expect instability in the Ropsten network and continue to avoid using it for ongoing testing not directly related to testing consensus-level issues and reorgs.

We are aware of potential consensus issues on the Ropsten testnet related to the upcoming London hard fork. After these issues are corrected in all likelihood the Ropsten network will be rolled back to block 10679536 or earlier. As such, we recommend avoiding using the Ropsten network for ongoing testing until these consensus issues are resolved and new clients released and deployed by miners and infrastructure providers.
