- Recently, it has been discovered many times that after newly installing the mobile cloud disk APP on the IOS system, the universal link c.139.com (for example: https://c.139.com/m/a/s/?p=L1t4) cannot be used. Pull up directly. After our internal monitoring and analysis, the situation is as follows:
- Monitoring data shows that recent visits to Apple’s CDN configuration files (https://app-site-association.cdn-apple.com/a/v1/c.139.com, https://app-site-association.cdn -apple.com/a/v1/yun.139.com), a 404 error is often reported, that is, obtaining the configuration file from Apple CDN back to the source c.139.com and yun.139.com fails. The number of alarms is 2-3 times a day, and each time lasts for 1-2 hours. As a result, newly installed or upgraded IOS mobile cloud disk clients during the corresponding period cannot pass c.139.com and yun.139.com. The domain name directly launches the APP.
- After our operation and maintenance inspection, there are no abnormalities in the c.139.com server file configuration and network, and the universal link of the client's project configuration is also correct.
- We need Apple's help to check whether there are any abnormalities in the routing of Apple's CDN nodes to 117.161.4.213, and to check whether there is instability in the CDN nodes.
Thank you so much.
