Error types
There are numerous reasons a website might be unreachable. Unlike other down checker sites, we try to ping AND load the website.
- Ping failed: there might be a network error in play, although not necessarily.
- Ping failed but a valid http status is returned: the site is reachable, server settings make ping fail.
- Ping successulf but no valid http status is returned: there is no network error here, an application level error might be the culprit.
- No valid http status: http status above 400 means that the server couldn't successfully serve the request.
- In some cases websites block DOJ.me so we report them as offline when they are in fact online. We can do nothing about it, only those websites can unblock us. We have measures in place not to overload other sites with too many checks.
- Sometimes we get mixed results or our requests time out. In such cases we can't be 100% sure if a site is up or not.
Troubleshooting Tips for O2online.de
