Status Check FAQ

• Why our public status pages are better than others?

  We rely on the combination of both automated checks and user reported issues. Quite often, purely automated uptime monitoring cannot provide the full picture.

• How often do you check if a service is down?

  If there are reported issues or interest in a specific service, we might check as frequently as every minute. However, we may check less frequently for services with less interest or fewer reported issues. For example, once every hour.

• What is the best way to report an issue?

  The easiest way to report an issue is to use the single-click light-yellow buttons at the top of this page. They represent the most common issues and are the fastest way to report an issue. Nevertheless, you can also use the 'Report an Issue' button or link at the top to report any issue you may have with the service. Also, you are more than welcome to use the comments box and discuss any tips, solutions or resolutions with the community.

• What is "Uptime Monitoring" and do you track it?

  Service Uptime Monitoring is a service that checks the availability of a website or service. It can be used to monitor the uptime and downtime of a website or service. Yes, we do track it, but we also rely on user reported issues to provide the most accurate status. Some of the benefits are: Early detection of service disruptions; Better communication with users; Increased reliability.
