Guides on uptime checks, SSL certificates, and downtime alerts for public websites.
- Monitor website uptime from your phone
You will not keep a laptop dashboard open all day. A mobile-first monitor shows up, down, and SSL status when you need it — without installing anything on the server.
- Website down email alerts — why you need them
Opening your own site is not a monitoring plan. An external check and a clear email are how you learn a URL is down before customers tell you.
- Simple website uptime monitoring — no server install
Paste your public URL and get scheduled checks from outside your host. Here is what a minimal uptime setup covers and what you can skip early on.

A 90-day certificate can expire when auto-renewal stops. Here is how to read a failed renewal, fix the usual causes, and know before the browser warning.
- How to check when an SSL certificate expires
Read the expiry date in a browser or with OpenSSL, and learn why a one-time look is not enough for sites you do not open every day.
- What happens when an SSL certificate expires
Browsers block the page with a security warning even if the server is still running. Here is what the expiry date means, and how to notice it before visitors do.
