If you tried resolving a DOI in the past hour or so (00:30 to 01:30 UTC on 2024-05-29), you may have received a timeout notice on the [doi.org](http://doi.org) domain:

 ![A DOI Foundation page reading "Error resolving DOI / connection timed out / The initial connection between Cloudflare's network and the origin web server timed out. As a result, the web page can not be displayed](https://us1.discourse-cdn.com/flex020/uploads/crossref/original/2X/3/381551e56942d42fd7bb2985a8ba11e140c18a82.png)

While the issue now appears to be **resolved** , the International DOI Foundation reports on their status site that:

> [doi.org](http://doi.org) resolution services were inaccessible for approximately an hour from 00:30 to 01:30 UTC on 2025-05-29 [sic].
> 
> The issue seems to be caused by some failure of Cloudflare’s “Load Balancing” product which is used by [doi.org](http://doi.org) to steer global traffic to appropriate backend servers. We have worked around this issue in order to restore [doi.org](http://doi.org) resolution services, but have yet to restore full geo-steering functionality or determine why the failure happened. We will add information as it becomes available.
