Description

Recently I've started getting intermittent 403 Forbidden responses from https://validator.swagger.io/validator/debug when running on GitHub Actions. (c.f. Job 79811483513):

HTTP/2 403
date: Fri, 05 Jun 2026 20:50:51 GMT
content-type: text/html
content-length: 118
connection: keep-alive

<html>
<head><title>403 Forbidden</title></head>
<body>
<center><h1>403 Forbidden</h1></center>
</body>
</html>

Perhaps this is due to IP-based rate limiting? Do you have recommended guidance for how projects using the validator should handle this scenario? Wait and retry? Don't use the validator from GitHub Actions (or CI pipelines in general)?

Thanks,
Kevin
