Of all XRD staked on the Radix network, 14% is still staked to validators running on servers provided by Hetzner, which has taken an anti-crypto stance. Hetzner recently decided to ban all Solana nodes hosted by their services. This action led to some concerns within the Radix community about the validators hosted by Hetzner. Some validators have taken action by switching to a new provider, but others seem to be waiting to see what happens.
It is possible that the validators still running on Hetzner have backup validators at other providers that will kick in if Hetzner ever decides to ban Radix validators as well. However, concerned delegators (stakers) can make their voice heard by reallocating their stake to non-Hetzner validators.
