Three locations, 5 different client types, no-downtime upgrades; this is what a professional staking setup looks like. With correlated downtime penalties coming in 2027 (🤞), high availability setups with client diversity and chain split protection will be a must for institutional stakers going forward.
Some detail on the setup, now live with the first deposits in: six Charon nodes across three sites, two per site. Duties need four, so a full site can go offline and the cluster keeps signing.
The same margin makes updates rolling instead of scheduled downtime.
