In 2021, the regulator of one of the world’s busiest securities markets rewrote its recovery clock.
Market infrastructure institutions, the exchanges, clearing corporations and depositories that a market actually runs on, had until then been allowed several hours to recover from a disaster, and a generous share of that simply to decide that one had occurred. The revised framework cut the whole thing to well under an hour: minutes to declare, and a fixed number of minutes from that declaration to be running live from the disaster recovery site. Tolerable data loss was halved. Institutions had a single quarter to comply.
Most of the commentary at the time was about the switchover. That is the visible part: the moment someone senior decides, and traffic moves to another building hundreds of kilometres away. But the recovery window is not when you copy the data. By the time that clock starts, the data has to already be there.
The full piece is what building that replication taught us, and how Solace File Mesh answers it.
