Liteserver Synchronization Instability

Over the past several days, multiple operators have reported liteserver synchronization issues.

Our analysis has identified several potential causes affecting block and external message propagation in public overlays. We have already deployed a number of mitigations to reduce the impact. However, a full resolution will require additional analysis and a validator update.

Expected Impact:

At this time, the impact appears to be limited primarily to smaller
third-party operators running a single liteserver. The blockchain
continues to operate within an acceptable range, transaction processing performance has not deteriorated, and major services and wallets continue to function normally.

We currently expect the validator update to take place on April 28. Some validators may be asked to update earlier.
