!!! note

If fast synchronization fails, usually because the node can't find enough valid peers, fast
synchronization restarts after a short delay.
When running Besu on certian cloud providers, a known [RocksDB](https://github.com/facebook/rocksdb/issues/6435)
issue causes fast sync to fail occassionally. The following error is displayed repeatedly:

```
...
EthScheduler-Services-1 (importBlock) | ERROR | PipelineChainDownloader | Chain download failed. Restarting after short delay.
java.util.concurrent.CompletionException: org.hyperledger.besu.plugin.services.exception.StorageException: org.rocksdb.RocksDBException: block checksum mismatch:
....
```

The failure has been seen on AWS and Digital Ocean. A full restart of the AWS VM is required to
restart the fast sync. Fast sync is not [currently supported on Digital Ocean](https://github.com/hyperledger/besu/blob/master/CHANGELOG.md#143).

!!! important

Using fast synchronization with
[private transactions](../../Concepts/Privacy/Privacy-Overview.md) is not supported.
Using fast sync with
[private transactions](../../Concepts/Privacy/Privacy-Overview.md) or on Digital Ocean Droplets
