A service engineer is trying to determine why one of the company's SaaS solution is no longer available. The internal systems are responding and other online applications using the same SaaS solution

A general cloud service provider outage would typically affect all or many customers of the SaaS solution, contradicting the observation that other applications using the same SaaS are working.

While automation issues can cause problems, an integration issue is a more specific and common cause when the SaaS platform itself is otherwise functional for other users.

When a specific SaaS instance is unavailable while the broader SaaS platform and other applications using it are functioning correctly, it strongly indicates a problem with the integration between the affected application and the SaaS. This could involve misconfigured API credentials, incorrect data formats, endpoint issues, or authentication problems specific to that integration.

A subscription issue would likely affect all or significant parts of a company's usage of the SaaS, not just one specific application while others using the same SaaS remain operational.
