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?

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.
SaaSHub's Down Detector checks the status of services automatically and regularly. However, we cannot promise 100% accuracy. That is why we depend on user reported issues as well. The YSlow status here can help you determine if there is a global outage and YSlow is down for everyone or if it is just you who is experiencing problems. Please report any issues to help others know the current status.
