The current SLA has a single 99.995% commitment; there are no separate replica-set vs sharded vs multi-region tiers on the page. Free/shared tiers (M0, Flex) and anything below M10 are not covered. 'We will provide at least 90 days' advance notice for adverse changes to this SLA.' The old URL mongodb.com/cloud/atlas/sla redirects here.
