1. 2025年6月12日 18:20 UTCinvestigating

   We're investigating an outage with the cdnjs API. We believe this to be caused by an upstream provider issue.

2. 2025年6月12日 18:34 UTCidentified

   cdnjs' API is impacted by an ongoing outage with Cloudflare services: https://www.cloudflarestatus.com/incidents/25r9t0vz99rp

3. 2025年6月12日 19:18 UTCidentified

   Cloudflare has indicated that it is beginning to see recovery of its services. We continue to monitor the impact to cdnjs' API and will provide an update when it has recovered.

4. 2025年6月12日 20:31 UTCmonitoring

   At this time, we're seeing cdnjs' API service recover and return to normal operation. We'll continue to monitor the service until the upstream provider indicates resolution and we're happy the service is stable.

5. 2025年6月12日 21:42 UTCresolved

   Cloudflare has now marked its incident as resolved, and we are confident that the cdnjs API is now operating as normal.

1. 2023年8月1日 18:22 UTCidentified

   We are aware of an issue impacting multiple libraries where SRI hashes have changed. We have found the cause of the change to the file contents/hashes and are actively working to restore the previous contents/hashes. No files on the CDN have been compromised, the contents/hashes have changed due to libraries being reprocessed with different minification logic. We are tracking this on GitHub in https://github.com/cdnjs/cdnjs/issues/14210

2. 2023年8月2日 18:26 UTCmonitoring

   A backfill has been completed that is believed to have restored files to their previous states, with the SRI hashes reverted to what they were prior to this incident. We'll continue to monitor for reports of any hash mismatches, which should be reported in the issue on GitHub at https://github.com/cdnjs/cdnjs/issues/14210

3. 2023年8月4日 15:33 UTCresolved

   At this time we believe the fix to restore file content and SRI hashes is working as expected.

1. 2022年5月20日 11:27 UTCinvestigating

   We are aware that the cdnjs API is returning 502 responses for many requests. We are investigating this issue. (Edit: This incident has been back-dated to the believed initial starting point of impact for requests. Incident was initially declared at 11:30 UTC.)

   The API service has now been restored.

1. 2021年5月24日 20:41 UTCinvestigating

   We are aware that the cdnjs API is currently returning a 502 Bad Gateway error for requests. We are investigating this and will update once we know more.

2. 2021年5月24日 21:20 UTCinvestigating

   We continue to investigate the 502 error issue with the API and are aware that this may also be impacting accessing library information on the cdnjs website as this is backed by the cdnjs API service.

3. 2021年5月24日 21:53 UTCmonitoring

   We have implemented a fix for the 502 issues -- the API service, as well as the website, appears to be operational once again. We will continue to monitor the situation to ensure this remains the case.

4. 2021年5月24日 22:02 UTCidentified

   We are aware of a secondary issue where some requests are receiving a 530/1016 Origin DNS error and we are working to resolve this.

5. 2021年5月24日 22:40 UTCmonitoring

   A further fix has been implemented and the API service appears to be healthy now. We will continue to monitor this.

4. 2020年8月12日 14:56 UTCmonitoring

   A fix has been implemented that should allow users in mainland China to access cdnjs. Cloudflare will continue to monitor the situation.

5. 2020年8月12日 15:26 UTCresolved

   At this time we are confident that access to the CDN has been restored for all users of cdnjs.

1. 2020年6月12日 8:30 UTCinvestigating

   We are aware of reports that some libraries on the cdnjs website and API are resulting in an error response. We have notified our team and are looking into the root cause of this issue.

2. 2020年6月12日 9:25 UTCidentified

   We have identified the source of the failure, the metadata used for the website and API for packages data was unable to generate correctly, resulting in the data used being corrupted. We are working to mitigate this and regenerate the data.

3. 2020年6月12日 10:30 UTCidentified

   The cdnjs API is now correctly responding to library requests, however, we are still working to resolve the issue present on the website.

4. 2020年6月12日 11:15 UTCmonitoring

   The cdnjs website and API are now both using updated packages metadata, allowing them to correctly respond to requests for libraries without error. We will continue to monitor both the API and website to ensure this doesn't happen again.

1. 2020年4月15日 19:01 UTCinvestigating

   We are aware of an issue affecting requests for certain assets resulting in a 522 or 523 response. We are currently investigating the source of this issue.

2. 2020年4月15日 19:28 UTCidentified

   We believe this is due to the ongoing incident Cloudflare has: https://cfl.re/2VbxQ96 - Requests to cached assets should work but any request for an asset not cached on cdnjs is likely to fail at present.

3. 2020年4月15日 20:03 UTCmonitoring

   It would appear the origins for cdnjs.cloudflare.com are now available again and requests to uncached cdnjs assets should now work as expected. We will continue to monitor for a while to ensure this is stable. For more information on the larger Cloudflare outage, please follow their status page updates: https://cfl.re/2VbxQ96

4. 2020年4月15日 21:50 UTCresolved

   We are confident at this time that all cdnjs assets are now available on the CDN once again. Cloudflare is continuing to see good recovery on their incident as well: https://cfl.re/2VbxQ96

1. 2019年12月30日 9:59 UTCinvestigating

   We have been made aware of an issue with the cdnjs website that means certain library pages are not showing, with an error message "version not found!" shown instead. Further, it appears that on the same libraries, their API responses do not contain the correct versions. This does not affect the libraries available on the CDN, cdnjs.cloudflare.com.

2. 2019年12月30日 15:33 UTCidentified

   We have identified the issue as a fault within our package generation script that feeds cdnjs repository information to our website & API. We are tracking this issue on GitHub: https://github.com/cdnjs/cdnjs/issues/13654

3. 2019年12月30日 15:35 UTCmonitoring

   We have now implemented a fix and believe that packages should now be showing correctly on the cdnjs website and via the API. We will continue to monitor this whilst the caches clear to ensure this issue is no longer present.

4. 2019年12月30日 17:19 UTCresolved

   We are now confident the fix is working as expected. The cdnjs website and API are now showing libraries and their versions correctly.

1. 2019年7月2日 13:53 UTCinvestigating

   We are aware of reports from users that cdnjs (website & CDN) is returning 502 Bad Gateway errors. We believe this is a larger issue with Cloudflare itself as many other websites behind them are also down. We will keep this updated as we know more.

2. 2019年7月2日 14:02 UTCinvestigating

   Cloudflare have now raised an incident on their status page due to the outage: https://www.cloudflarestatus.com/incidents/tx4pgxs6zxdr

1. 2019年6月24日 11:28 UTCidentified

   We have been made aware of some users who are having connectivity issues to both our main website and the CDN service. We believe at this time that this is due to network issues that Cloudflare are experiencing. This is likely to also impact our API, though we have no reports of this yet. You can track the Cloudflare incident at https://www.cloudflarestatus.com/incidents/46z55mdhg0t5

2. 2019年6月24日 11:57 UTCidentified

4. 2019年2月6日 16:13 UTCidentified

   Further reports have been made of continued issues with the CDN and these have been passed on to Cloudflare to ensure that the issue is resolved in a timely manner. We apologise for the drop in service to those affected.

5. 2019年2月6日 16:15 UTCmonitoring

   This issue had resurfaced due to an automatic process with Cloudflare reinstating a broken node into the load balancer. This has now been stopped and we will continue to monitor to ensure the CDN is performing normally.

6. 2019年2月6日 16:17 UTCresolved

   We believe that the CDN is now back to normal and service should be fully restored to cdnjs! Apologies from all of us here at cdnjs for the delay in getting this resolved and for the drop in service. Have a great weekend making use of cdnjs in all your projects!

1. 2019年2月6日 15:34 UTCinvestigating
