Notice October 16, 2026 Sandbox Environment – Intermittent Downtime During Hosting Provider Maintenance 11h 3m Sandbox Website, Sandbox API
Started Oct 16, 2026, 07:06 PM UTC· resolved Oct 17, 2026, 06:10 AM UTC
- investigating Oct 16, 2026, 07:06 PM UTC
Our hosting provider is performing emergency platform-wide maintenance that requires rolling restarts of its servers in all regions. As a result, the sandbox web application may be intermittently unavailable or slow to respond. Each restart is expected to cause roughly 15–20 minutes of downtime, and more than one interruption may occur while the rollout continues. Production environments are not affected. No action is needed on your part. If a request fails, please retry after a few minutes. Data in the sandbox is not expected to be lost. We are tracking the provider’s progress and will post an update when maintenance is complete and the sandbox is stable.
- monitoring Oct 16, 2026, 07:22 PM UTC
The hosting provider’s maintenance is complete and the sandbox web application is available. We are monitoring for further issues. If you still see errors, please contact support.

Minor February 18, 2026 Intermittent DNS Resolution for Certain ALIAS Records 1h 42m Name Servers
Started Feb 18, 2026, 02:24 PM UTC· resolved Feb 18, 2026, 04:07 PM UTC
- monitoring Feb 18, 2026, 02:24 PM UTC
Starting at 08:35 UTC, we are experiencing intermittent DNS resolution issues affecting a subset of ALIAS records that point to hostnames within the same zone. Earlier today, we began rolling out improvements to our alias resolution handling. During the deployment, a bug was introduced that manifests when an ALIAS record targets a name inside its own zone. Because the updated logic is not yet fully deployed across all authoritative nameservers, affected records may resolve inconsistently depending on which nameserver handles the query. This is resulting in sporadic resolution degradation for impacted ALIAS records. We have identified the issue and are currently rolling back the changes across the affected authoritative nameservers. We are actively monitoring resolution behavior as the rollback progresses. We will provide further updates once the rollback is fully complete and resolution behavior has stabilized. We apologize for the disruption and appreciate your patience.
- resolved Feb 18, 2026, 04:07 PM UTC
The rollback has completed, and DNS resolution has returned to normal behavior. We will be making follow-up improvements to alias-resolution handling, including additional safeguards and testing to prevent recurrence.
