What Is Uptime?
Uptime is the percentage of time a service is operational and accessible. A 99.9% uptime means the service is down for no more than 8.76 hours per year. For domain forwarding, uptime determines how reliably visitors are redirected.
Why It Matters
If your redirect service is down, every visitor to your forwarded domain hits a dead end. For domains used in marketing campaigns, vanity URLs, or brand migrations, even minutes of downtime means lost visitors and lost revenue.
Uptime Percentages Explained
| Uptime | Downtime/Year | Downtime/Month | Downtime/Week |
|---|---|---|---|
| 99% | 3.65 days | 7.31 hours | 1.68 hours |
| 99.9% | 8.76 hours | 43.83 minutes | 10.08 minutes |
| 99.99% | 52.6 minutes | 4.38 minutes | 1.01 minutes |
| 99.999% | 5.26 minutes | 26.3 seconds | 6.05 seconds |
What Causes Downtime in Forwarding
| Cause | Impact | Mitigation |
|---|---|---|
| Server failure | All redirects on that server stop | Redundancy / CDN |
| SSL certificate expiration | HTTPS redirects fail | Auto-renewal (Let’s Encrypt) |
| DNS issues | Domain doesn’t resolve | Multiple nameservers |
| DDoS attack | Service overwhelmed | Traffic filtering |
| Network outage | Connectivity lost | Multiple edge locations |

Frequently
asked questions
Domain Forward maintains 99.9% uptime for redirect services. Our global edge network provides redundancy — if one node goes down, traffic is automatically routed to the next nearest node.
Visitors see an error page (typically a timeout or connection refused) instead of being redirected. For any domain that receives consistent traffic, forwarding uptime is critical.
