GeoIP from sanctioned country
Seems like outdated and wrong geo IP data can affect your infra in weird way.
I found that requests to Sentry and Incident (third parties) were failing from pods running on certain nodes. It turned out that both Sentry and Incident run on Google Cloud Platform (GCP) which had blocked the IPs that had been assigned to those nodes.

Unfortunately, some GeoIP databases incorrectly locate some of our IPs in Iran. We cannot influence these databases.
