1C remains the system of record for most remaining Russian subsidiaries. Access from the United States has become a network problem as much as an accounting one: hoster IP filters, VPN blocks, and a single on-prem box with no off-site copy. When a liquidation or an FTS objection starts, the first week is often “we cannot open the file.”
The structure we run is two estates. The affiliate administers dedicated servers in Russia. A mirror in the United States receives a scheduled replica (72 hours by default; daily if the books still move). Finance and audit in HQ authenticate to the U.S. side, with roles and a connection log. They do not open a session on the Russian segment.
That is also a sanctions-architecture choice. A U.S. person on a Moscow LAN is a fact pattern you should not need. Replication plus a U.S. access plane is slower than a live remote desktop into Russia, and that is acceptable. Dormant books do not need live. They need recoverable.
Takeaways
- Ask where the only copy lives before you staff a wind-down.
- Default replica every 72 hours is enough for most dormant ledgers.
- 2FA and a user list from HQ — not a shared “director” password.
