When a website stops loading, your first thought is usually that the server is down. But server issues can look identical to browser problems, DNS failures, or network blocks. The real challenge is figuring out whether the server itself is offline—or if something else is breaking the connection. Most people miss one crucial step that instantly reveals the truth…
Need a fast answer? Try our uptime checker to instantly see whether the website’s server is responding globally.
Server issues often produce specific browser errors like:
Clue: these errors usually mean the server is overloaded or offline.
If the site loads on mobile data but not on Wi-Fi, the problem is likely your network—not the server.
If it fails everywhere: the server may truly be down.
Many outages come from hosting providers experiencing downtime. Popular hosts like Hostinger, GoDaddy, Bluehost, and SiteGround occasionally have service interruptions.
Clue: multiple websites on the same host fail at once.
DNS problems can make a server appear offline even when it’s running perfectly. If DNS records are outdated or misconfigured, your browser won’t know where to find the server.
Common DNS-related errors: “Server not found,” “DNS_PROBE_FINISHED_NXDOMAIN.”
If the server responds in one region but not another, the issue may be related to routing or regional blocks.
If the site loads with a VPN: your ISP may be having routing issues.
When major websites go down, social media platforms like Twitter (X) often explode with reports. This can help confirm whether the outage is widespread.
Note: social media is helpful but not always accurate.
To know for sure whether a server is online, you need to test it from multiple global locations. This reveals whether the server is responding, slow, overloaded, or completely offline.
Try our uptime checker — it gives you an instant yes/no answer based on real-time server response.
Server outages can be caused by overload, hosting failures, DNS issues, or regional routing problems. Understanding how to test server status helps you quickly identify whether the issue is global or local.
