Check if TimeRex is down, official outages, user-reported issues, and outages map.
TimeRex is working normally
Check the number of user-reported issues over the past 24 hours, grouped into 20-minute intervals. It's normal to see occasional reports, which may be due to individual user issues rather than a broader problem. We only consider an issue widespread if there are multiple reports within a short timeframe.
 
    IsDown has tracked 11 incidents since started monitoring TimeRex status in April 2024. We collect data from 4522+ services, and normalize the data to give you a clear picture of the impact of the outage. It will show official TimeRex outages and also issues that we're started by a spike in crowdsource reports.

Monitoring TimeRex since April 2024
Tracking 10 TimeRex services and regions
2 incidents in 2025
IsDown is a status page aggregator that monitors if TimeRex and all your dependencies are experiencing issues. We combine the status of all the services you dependent and provide a clear view of all your vendors health in one place. We not only monitor official information but also crowdsourced reports. That means that even when TimeRex, per example, doesn't report an outage, you will still be notified if other users are experiencing issues.
Every few minutes we go to the status page of TimeRex (and 4,522+ other services) and check if they are experiencing issues. We collect the status and outage information of TimeRex's 10 components. Also, we not only monitor official sources but also user reports. Sometimes or a lot of times vendors take some time to report an incident, so by monitoring user reports we're able to alert you early.
Not only you will get notified, but IsDown offers notification filters, so you can choose which issues you want to be notified about. This way you avoid getting all the incidents from TimeRex and other services.
 
            IsDown checks TimeRex official status page for major/minor outages or downtimes. A major outage is when TimeRex experiences a critical issue that severely affects one or more services/regions. A minor incident is when TimeRex experiences a small issue affecting a small percentage of its customer's applications. An example is the performance degradation of an application. The moment we detect a TimeRex outage, we send you an alert and update your dashboard and status page.
TimeRex and other vendors don't always report outages on time. IsDown collects user reports to provide early detection of outages. This way, even without an official status update, you can stay ahead of possible problems.
IsDown collects all information from the outages published in TimeRex status page to provide the context of the outage. 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.
TimeRex 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 TimeRex and all their 10 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.
Our tool was build to be the best way to monitor all your external dependencies in one place. IsDown not only will help you monitor TimeRex but also 4,522 other services. Your team and customers will have a clear view of all your dependencies and their status, making it easier to identify and resolve issues.
Add all your dependencies to your dashboard. IsDown will monitor them in real-time and send you alerts when there is an issue. You can also create a status page for a bird-eye view and share it with your team.

                        While Downdetector relies on user-submitted reports to detect TimeRex outages, IsDown monitors TimeRex's status page for verified, detailed incident information. Here's why official monitoring provides better reliability for your business:

IsDown monitors the TimeRex official status page every few minutes. We also get reports from users like you. If there are enough reports about an outage, we'll show it on the top of the page.
TimeRex last outage was on October 29, 2025 with the title "「The given data was invalid.」「he specific day availabilities field is required when has specific available days is 1.」などのアラートが表示され、日程調整カレンダーの作成/更新ができないなどの不具合が発生しております。"
Because IsDown is a status page aggregator, which means that we aggregate the status of multiple cloud services. You can monitor TimeRex and all the services that impact your business. Get a dashboard with the health of all services and status updates. Set up notifications via Slack, Datadog, PagerDuty, and more, when a service you monitor has issues or when maintenances are scheduled.
IsDown and DownDetector help users determine if TimeRex 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 instead of just relying on reports from users. The integration allows us to provide more details about TimeRex's Outages, 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.
