High latency in the api/v4/groups

In the company where I work, we noticed that the latency for the group API increased, from less than 1 second to over 6 seconds, it started happening on December 2nd, 2022, the API increased the response time for a specific request as it’s possible to see on the image:

We know that seems that it is a known issue (Improve latency of /api/:version/repos/:namespace/:project/pulls (#337269) · Issues · GitLab.org / GitLab · GitLab, we saw other places have mentioned some issues with CloudFlare), but we are wondering why are we getting impacted by this now, wondering if there were some changes recently released because we have some automated test that checks this flow where we are calling this API, and they had been working without any problems since we added them (about 4 months ago) but started failing on December 2 as I mentioned.
