Seeing repeated access to [comet-test-fr.s3.eu-central-1.amazonaws.com] -from Comet flagged as Phishing

My firewall is flagging this URL comet-test-fr.s3.eu-central-1.amazonaws.com as being bad. It could simply be a misclassification. I've searched and only found maybe/sortof/might-be explanations for how it might be part of Comet's telemetry data.

Curious if others have already been thru this w/ Comet.

Thanks.
