Customer databases are hosted in the closest Odoo data center. EMEA—France, Americas—Canada, APAC—Hong Kong. Each customer instance is replicated in real-time on a hot-standby system located in the same data center. Odoo works with different hosting providers worldwide (and can switch at any time), but they always deliver at least a 99.9% uptime guarantee. So they can guarantee a minimum of 99.9% uptime (3 nines, excluding planned maintenance). This corresponds to a maximum unplanned downtime of 1.44min/24h or 8h/year. Odoo usually delivers much better uptime than this (100% most months), and their providers always deliver a much better uptime than their SLA, too.
The data centers where Odoo is hosted are Tier-III certified or equivalent, with N+1 redundancy for power, network, and cooling. Each customer database is replicated in real-time on a hot-standby server located in the same data center.
