Service Level Agreement
Last Revised: August 7, 2021
The Service is currently hosted on Amazon Web Services ("AWS"). The Service will be available 100.00% of the time that AWS and sub-vendors are functioning correctly.
There has been no Service maintenance downtime, ever. Should such downtime ever become necessary, Provider will use its best efforts to notify all account owners by email of the scheduled maintenance date and window and purpose.
If any User does not experience the promised level of availability, and User provides convincing proof that such failure is attributable to a fault in the Service and not to any other cause (and is therefore a "Service Failure"), Provider will allow User to cancel the service and receive a pro-rata refund of the lesser of the remaining unused time or the remaining unused Credits.
Lifetime Uptime: 99.99997%

On 2019/09/27 at 10:01 AM EST, a customer sent the US SaaS system requests at more than 1,000 times the allowed throughput. This caused intermittent timeouts for some US based customers until the system was fully stabilized by 10:34 AM EST. Normally we are able to stop such problems before they overwhelm all of our servers, but this time we bungled our response, resulting in intermittent outages for approximately 33 minutes. As a result of this incident, Provider wrote an AI layer to continuously monitor and automatically protect the Service in realtime. Since implementation of SovProtect in February of 2020, there have been 0 minutes of Service outage or degradation, worldwide.
Lifetime 100% Performance: 99.9999% (zone adjusted)
Periods of reduced performance:
|2020||100 minutes||AI Matching||Intermittent slowness and timeouts in AI Matching due to a hardware failure in third party vendor's systems|
|2019||75 minutes||AI Matching||Slowness and occasional errors in one availability zone in AI Matching due to third party vendor's systems|
|2018||195 minutes||Conversion for parsing||Partial outage related only to conversion of some PDF documents in one availability zone; attributable to third party software (fixed)|
In the event that AWS changes, discontinues, deprecates or terminates its services in a way that adversely impacts Sovren’s ability to continue the Service, Sovren reserves the right to change or terminate the Service. Sovren will give Users as much notice as reasonably possible and, in the event of a termination of Service, will provide User a pro-rata refund of the lesser of the remaining unused time or the remaining unused Credits.
