Codeberg restriction on viewing issues in specification repository

When I try to view page 2 of the list of open issues in 
https://codeberg.org/XProc/specification/issues, I instead see this message:

> Search and filtering is seeing a high influx of requests for this repository, to preserve the availability of Codeberg your search request will not be processed. Sorry for the inconvenience and please try again later.


The same happens if I try to search the issues.
