#Troubleshooting

Troubleshooting is the step-by-step process of finding the real cause of a problem instead of guessing at fixes. For websites and e-mail that means reading error messages, headers, logs and DNS records carefully. A good troubleshooting routine starts with the simplest checks and changes one thing at a time. It also records what was changed, so that a fix can be confirmed or reversed. The articles under this tag walk through common failures and the checks that reveal their causes.
