SMS, Telegram or Bale? Choosing Alert Channels Without Alert Fatigue
Which downtime alerts should go by SMS and which to Telegram or Bale, how to route by urgency, and how to keep the important alerts from drowning in noise.
How to check if a website is down.

Summarize in:
A site that won't open might be down for everyone - or only for you, because of your internet connection, DNS or browser. These steps tell the two apart in a few minutes.
1. Check it from somewhere else
Use our free website down checker: it opens the address from our servers and tells you the HTTP status and response time. If it works for us but not for you, the problem is on your side (network, DNS, VPN or browser).
Downtime happens. Get notified!
noc724 checks your websites, servers and APIs around the clock and alerts you by SMS, Telegram or Bale the moment something breaks.
2. Rule out your own connection
- Open the site on mobile data instead of Wi-Fi.
- Try another browser or a private window to skip the cache.
- Turn off any VPN or proxy and try again.
- Open another well-known site to make sure your internet works.
3. Read the error
| What you see | What it usually means |
|---|---|
| DNS_PROBE / 'server not found' | The domain doesn't resolve: DNS problem or expired domain. |
| Connection timed out | The server doesn't answer: overloaded, down or blocked by a firewall. |
| 500 / 502 / 503 / 504 | The server answers but the application behind it has failed. |
| 404 | The server works, but that page doesn't exist. |
| Certificate / privacy warning | The SSL certificate is expired or invalid. |
4. Stop checking by hand
Checking manually means you find out late - often from a customer. An uptime monitor checks your site around the clock and alerts you the moment it fails: noc724 sends SMS, Telegram and Bale alerts and keeps a history of every incident.
Frequently asked questions
Usually because of your connection: a local network or ISP issue, cached DNS, a VPN, or a browser extension.
Add the site to an uptime monitoring service such as noc724; it checks the site regularly and alerts you when it goes down and when it's back.
