Ultra Web Hosting offers a 99.9% uptime guarantee on all hosting plans. Here is what that means in practice, what happens if we fall short, and how we keep our servers running reliably.
99.9% uptime means less than 44 minutes of downtime per month
We monitor our servers 24/7 and our infrastructure is designed with redundancy at every level: redundant power, redundant network connections, RAID storage, and automatic failover. Scheduled maintenance windows are announced in advance and performed during off-peak hours.
01. What Counts as Downtime
Our uptime guarantee covers server and network availability. This means the server your account is on is powered on, connected to the internet, and responding to requests. The following are counted as downtime:
- Server hardware failures that take your site offline
- Network outages within our data center
- Unplanned server reboots
What does not count
- Scheduled maintenance - We announce planned maintenance in advance. These windows are typically brief and scheduled during low-traffic hours.
- Your site's own errors - PHP errors, misconfigured .htaccess files, exceeded resource limits, or WordPress plugin issues are not server downtime. See Error 500 and Error 508/503 Resource Limit Reached for troubleshooting.
- DNS propagation - If you recently changed nameservers, your site may not be visible to all visitors for up to 48 hours. This is a DNS issue, not a server issue. See DNS Changed But Site Not Showing.
- DDoS attacks - While we have DDoS mitigation in place, massive attacks beyond our mitigation capacity are considered force majeure.
02. How We Achieve High Uptime
Our infrastructure is built for reliability. For the full details on our hardware, network, and data center, see Ultra Web Hosting Infrastructure and Network.
- Redundant power - Dual power feeds, UPS battery backup, and diesel generators
- RAID storage - All drives are in RAID configurations so a single disk failure does not cause data loss or downtime
- Redundant network - Multiple upstream providers so a single carrier outage does not take us offline
- 24/7 monitoring - Automated systems alert our team to issues before they affect customers
- Regular backups - Server-level backups protect against catastrophic data loss
03. If We Fall Short
If our servers experience downtime that causes us to miss our 99.9% uptime commitment during any calendar month, you may be eligible for a service credit. To request a credit, open a support ticket within 7 days of the incident and reference the downtime period. We will verify the outage against our monitoring data and apply the appropriate credit to your account.
If your site seems down but other sites on the internet are working fine, it may be a local issue. Use our Up or Down checker to test whether your site is down for everyone or just for you. Your IP might also be temporarily blocked by the firewall. Check with our Firewall Unblock tool.
