nacre.sh Uptime & Reliability: What You Need to Know

OpenClaw hosting uptime directly determines how useful your agent actually is. An agent that misses messages while you're asleep, fails to execute scheduled tasks, or drops your Telegram connection during peak hours is far less valuable than one that's genuinely always on. nacre.sh's reliability record and architecture are worth examining carefully before you commit your production workflows to the platform.

Historical Uptime Performance

nacre.sh's public status page (status.nacre.sh) shows month-by-month uptime across all three regions. Over the past 12 months, all regions have maintained above 99.9% uptime, with most scheduled maintenance windows communicated at least 72 hours in advance and completed during off-peak hours for each region's time zone.

99.9% uptime translates to approximately 8.7 hours of downtime per year. For a personal AI agent handling non-critical tasks, this is more than sufficient. For business-critical automations, nacre.sh's higher tiers offer enhanced SLAs.

Architecture That Supports Reliability

nacre.sh runs on a multi-availability-zone architecture within each region. Your instance isn't tied to a single server — if the physical host experiences hardware failure, your container is automatically migrated to a healthy node. This typically completes in under 60 seconds, producing the brief blips you might occasionally notice in response times rather than extended outages.

Nightly backups to Cloudflare R2 ensure that even in a catastrophic failure, your agent's memory and configuration can be restored. Cloudflare R2 itself has independent redundancy across multiple data centers.

Automatic Restart Behavior

OpenClaw processes occasionally crash due to memory pressure, plugin errors, or unusual input. nacre.sh monitors each instance with a health check every 30 seconds. If an instance fails to respond, it's automatically restarted. Most crashes result in less than 60 seconds of downtime, and the agent's conversational context is preserved across restarts from the last checkpoint.

Maintenance Windows

nacre.sh performs planned maintenance for major OpenClaw updates and infrastructure work. Maintenance is announced 72 hours in advance via dashboard notification and email. Typical maintenance windows last 15–30 minutes. Security patches (like CVE-2026-25253) are applied during off-peak hours where possible but may be deployed immediately for critical severity vulnerabilities.

What Happens When Something Goes Wrong

nacre.sh's support team is available 24/7 for severity-1 incidents (complete instance unavailability). For the US and Europe regions, most incidents are resolved within one hour. Singapore support response times are slightly longer but trending toward 24/7 coverage.

The nacre.sh status page is updated within 5 minutes of any incident affecting multiple customers. Individual instance issues are surfaced via dashboard alerts.

Frequently Asked Questions

What is nacre.sh's SLA?

The standard SLA for the base tier is 99.9% monthly uptime. Higher tiers include 99.95% or 99.99% SLA commitments with service credits for failures.

Does downtime affect my agent's memory?

No. OpenClaw state is checkpointed continuously to persistent storage. When your instance restarts after downtime, it picks up from the last checkpoint with no memory loss.

Can I monitor my own instance's uptime?

Yes. The nacre.sh dashboard includes an uptime graph for your instance. You can also configure webhook alerts to your Slack or Discord when your instance experiences downtime.
