+## What happens if it’s below 99.99%?
 Our Ops team is working so that we won’t find ourselves in that situation. But stuff happens, so if our uptime drops below 99.99%, we will provide an automatic credit under our SLA to our Big customers on their next billing cycle. For any given day where an outage exceeds 5 minutes, we’ll credit your account 10x for a full hour that is equal to the hourly rate you pay us for use of Basecamp.  You can always check up on us [here][uptime]. That is the full limit of our liability under this SLA. Now you can get back to your work with the peace of mind knowing that we’ve got you covered.
