IsDown and DownDetector help users determine if a service is having problems. The big difference is that IsDown is a status page aggregator. IsDown monitors a service's official status page to give our customers a more reliable source of information. The integration allows us to provide more details about the outage, like incident title, description, updates, and the parts of the affected service. Additionally, users can create internal status pages and set up notifications for all their third-party services.
IsDown offers an easy way to monitor Twilio with maximum flexibility
IsDown monitors PSTN for major outages. A major outage is when PSTN experiences a critical issue that severely affects one or more services/regions. When Twilio marks an incident as a major outage, IsDown updates its internal status, the customer status page and dashboard. Depending on the customer settings, IsDown will also send notifications.
IsDown monitors Twilio status page for minor outages. A minor outage is when PSTN experiences a small issue affecting a small percentage of its customer's applications. An example is the performance degradation of an application. When a minor outage occurs, IsDown updates its internal status and shares that information on the customer status page. Depending on the customer settings, IsDown will also send notifications.
IsDown collects all information from the outages published in Twilio status page to provide the most accurate information. If available, we gather the title, description, time of the outage, status, and outage updates. Another important piece of information is the affected services/regions which we use to filter the notifications that impact your business.
Twilio publishes scheduled maintenance events on their status page. IsDown collects all the information for each event and creates a feed that people can follow to ensure they are not surprised by unexpected downtime or problems. We also send the feed in our weekly report, alerting the next maintenances that will take place.
IsDown monitors Twilio and all their 124 components that can be affected by an outage. IsDown allows you to filter the notifications and status page alerts based on the components you care about. For example, you can choose which components or regions affect your business and filter out all other outages. This way you avoid alert fatigue in your team.
Twilio and other vendors don’t always report outages on time. Our crowdsourced status platform helps you stay ahead of outages. Users report issues and outages, sharing details on what problems they are facing. We use that info to provide early signs of outages. This way, even without an official update, you can stay ahead of possible problems.
