Uptime Commitment
Series guarantees 99.99% monthly availability for the production environment. Availability is measured by automated monitoring systems using five global probes checking service reachability every sixty seconds.
Downtime occurs when all standard API endpoints and the web application return HTTP 5xx errors or fail to respond within thirty seconds for more than one minute. Customer network issues, ISP problems, or configuration errors don't count toward downtime calculations.
Exclusions
The availability guarantee excludes:
Planned maintenance (maximum 4 hours monthly with 48-hour notice)
Force majeure events
DDoS attacks exceeding third-party scrubbing capacity
Upstream cloud provider failures during active failover procedures
Service Credits
Paying customers can request credits within 30 days if monthly availability falls below 99.99%:
99.9% to 99.99%: 10% credit
99% to 99.9%: 25% credit
Below 99%: 50% credit
Credits apply to your next invoice and represent your sole remedy for availability failures. Free tier users aren't eligible for credits.
Infrastructure
Series operates across multiple cloud providers (Google Cloud, AWS, IBM Cloud, Hetzner, Linode) with Akamai edge services, Imperva DDoS protection, and Arkose Labs fraud prevention. Geo-redundant replication enables automated failover without data loss.
Modifications
Series may update this SLA but won't reduce obligations during active subscriptions. Changes take effect 30 days after email or in-app notification and will be posted here.
This SLA is governed by West Virginia law and supersedes other agreements solely regarding service-level matters.
