Website Monitoring for Hosting Providers
Your uptime promises mean more when an independent third party backs them up. Oh Dear monitors your clients' sites from outside your infrastructure, giving you verified proof of performance.
Differentiate your hosting with monitoring that goes beyond "the server is running."

Independent uptime verification
Anyone can claim 99.9% uptime. We verify it from outside your network, giving clients confidence that the numbers are real. When prospects ask about reliability, you have independent data to back it up.
Checks run every minute from multiple global locations, so you catch issues before clients report them.
Showcase your server performance
Fast hosting is a selling point. We track response times across all client sites so you can show real performance data, not marketing claims. When you optimize configs or add caching, the numbers prove it.
Set performance budgets and get alerts when sites slow down, so you can fix issues before clients notice.
Monitor your own infrastructure
Monitor your MySQL servers, Redis instances, mail servers, and any TCP service your infrastructure relies on. Know when a database port stops responding before it cascades into customer complaints.
ICMP ping monitoring covers servers that don't have HTTP endpoints, giving you full visibility into your stack.
Go beyond basic hosting
Most hosts just keep the server running. We crawl client sites daily and catch broken links, mixed content, and missing images. It's an easy way to differentiate your offering and show you care about more than uptime.
When a client's CMS update breaks something, you can alert them before their visitors hit 404 pages.
SSL and domain expiration alerts
If you provision Let's Encrypt certificates or manage domains for clients, we monitor expiry dates and alert before anything lapses. No more emergency renewals or browser security warnings.
We also catch SSL chain issues and misconfigurations that cause intermittent HTTPS failures.
Status pages that stay up
When your hosting infrastructure goes down, your status page shouldn't go with it. Our status pages run on separate infrastructure, so clients can check status even during major outages.
Clear incident communication reduces support tickets and builds trust during the moments that matter most.

Frequently asked questions
Is Oh Dear a good fit for a hosting or managed-services provider?
Yes. You get independent, third-party uptime and performance monitoring that your customers will trust precisely because it is not your own dashboard, plus TCP-port and ping checks for the services behind HTTP like MySQL, Redis, SSH, and mail, and hosted status pages on separate infrastructure that stay up during an outage. It is monitoring you can put in front of customers, not just use internally.
Should we build our own monitoring or use Oh Dear?
Building it is the easy 80%, a cron that curls a URL, and the painful 20% is what matters: checking from multiple regions, verifying failures so you do not cry wolf, monitoring SSL, DNS, domains, and non-HTTP ports, and keeping a status page online when your own network is the thing that is down. Oh Dear is that 20%, maintained, for less than the engineering time it takes to half-build it.
Why do I need independent uptime monitoring?
Anyone can claim 99.9% uptime. Oh Dear verifies it from outside your network, giving clients third-party proof that your numbers are real. When prospects ask about reliability, you have independent data to back it up. This builds trust and differentiates you from competitors who only self-report.
Can I resell Oh Dear monitoring to my hosting clients?
Yes. Our reseller program lets you bundle Oh Dear with your hosting plans. You can also use our API to provision monitoring automatically when clients sign up. Alternatively, our affiliate program lets you earn commission by referring clients. Either way, you add value and generate revenue.
How do status pages help during outages?
When your hosting infrastructure goes down, your status page shouldn't go with it. Our status pages run on separate infrastructure, so clients can check status even during major outages. Clear incident communication reduces support tickets and builds trust during the moments that matter most.
Can I monitor services beyond HTTP like MySQL and Redis?
Absolutely. We monitor any TCP service on any port. When MySQL on 3306 stops responding or Redis on 6379 goes silent, you get alerted before it cascades into customer complaints. ICMP ping monitoring covers servers without HTTP endpoints, giving you full visibility into your infrastructure stack.
How can I prove my hosting is faster than competitors?
We track response times across all sites on your platform. When you optimize configs or add caching, the performance data proves it. You can share this data with prospects and clients as evidence of your infrastructure quality. Real numbers beat marketing claims.
Do you publish your monitoring IP addresses for firewall whitelisting?
Yes. We publish a fixed list of static IP addresses that our monitoring checks originate from. You can whitelist these IPs in your firewalls and security configurations. View our complete IP list.
