ABOUT THE SITE
Clearer next steps when a website fails
erriscope.com explains what website errors mean, helps you distinguish likely causes, and shows how to verify whether a troubleshooting step worked.
What erriscope.com publishes
erriscope.com is a reference for diagnosing website errors and common hosting, browser, DNS, SSL, and WordPress problems. The guides are designed for the point when a site stops responding or an unfamiliar message appears and you need a focused next step—not an unprioritized list of possibilities.
A useful guide should help you:
- Identify the exact error and what you are likely to observe
- Separate the most plausible causes from less likely explanations
- Run checks that distinguish between those causes
- Apply a proportionate fix suited to the relevant environment
- Verify whether the original symptom has cleared
- Recognize when the issue requires a hosting provider, developer, or site administrator
The guide collection covers HTTP responses such as [500 Internal Server Error](/guides/http-500-internal-server-error) and [502 Bad Gateway](/guides/http-502-bad-gateway), browser and DNS errors such as [DNS_PROBE_FINISHED_NXDOMAIN](/guides/dns-probe-finished-nxdomain), SSL and connection failures, and WordPress configuration problems.
Editorial policy
Published guides use a consistent diagnostic structure and are expected to include a named reviewer and review date. Draft, placeholder, and incomplete material is kept out of the public search index. When guidance changes, its review date and revision history can be updated in the administration area.
Before publication, technical guidance is reviewed for clarity, plausibility, and practical verification steps. Procedures that depend on a particular hosting environment, software configuration, DNS provider, or level of administrator access should identify that dependency rather than presenting one procedure as universal.
Because software and hosting environments change, a previously correct instruction may become incomplete or unsuitable. Check that a suggested change fits your environment, and report guidance that is inaccurate, outdated, or unclear through the [contact page](/contact).
What the website status checker measures
The website status checker makes one safe diagnostic request to the public website address you submit. Its purpose is to indicate whether the hostname is reachable from the checker’s server at that time.
This is a limited, point-in-time reachability test—not a general-purpose scanner or a complete availability measurement. A result from one server cannot establish that a site is available from every region, network, device, page, or feature path.
If the checker reports a problem, compare that result with what you observe locally and continue with the relevant error guide. If it reports that a site is reachable while you still cannot use it, investigate differences in local DNS, browser, network, authentication, or application-specific behavior.
Corrections and feedback
When reporting a correction, identify the affected guide, quote or describe the step or claim that appears incorrect, and explain what you observed instead. Include relevant software, hosting, or configuration details only when it is safe to share them.
You can also review the site’s [Privacy Policy](/privacy) and [Terms of Use](/terms).
Frequently asked questions
Is erriscope.com an official support site for a hosting provider or software product?
No official affiliation or product-support relationship is stated here. erriscope.com provides independent explanatory guides for common website errors and diagnostic situations.
What does the website status checker actually test?
It makes one safe diagnostic request to the public website address you submit. The result describes reachability from the checker’s server at that time; it does not scan the site or prove that every visitor, region, page, or service feature can access it.
Why might the checker say a site is reachable when I cannot open it?
The checker and your device may use different networks, DNS resolvers, routes, or locations. Your problem may also affect a specific page, browser, account, or application feature rather than the public hostname.
How are erriscope.com guides reviewed?
Published guides follow a consistent diagnostic structure and are expected to have a named reviewer and review date. Technical claims and recommended steps are reviewed for clarity, plausibility, and practical verification before publication. Updated guides can have their review date and revision history changed.
What should I include when reporting a correction?
Use the [contact page](/contact). Identify the guide, the step or claim that appears incorrect, and what you observed instead. Relevant software, hosting, or configuration details can help, but do not share credentials or other sensitive information.
Can a guide guarantee that a fix will solve my error?
No. Website errors can have different causes in different environments. The guides are intended to help you test plausible causes, make an appropriate change, and verify the result—not to present one fix as universal.
