Hey Pedro, my name is Jonathan and I’m part of Prefect’s security team.
This address appears to be in
Google’s IP space, but does not match the IPv4 addresses of any of our endpoints used by Prefect Cloud (
api.prefect.io is 34.111.157.195 and api.prefect.cloud is 34.111.36.90).
It’s possible that it’s related to our anonymous telemetry, yes, because that uses Cloud Run, which does not have a fixed IP address. The hostname is
sens-o-matic.prefect.io but I think the IP address may change (this is a CNAME to
ghs.googlehosted.com). It’s also possible that other libraries you’re using are sending some telemetry to Google, so may be tricky to isolate.
I’m happy to support your investigation in any way that we can; you can reach us via
security@prefect.io
