There has been an alert that some monitoring stations IP are not listed as in Europe: this is unexpected and causes a security issue, monitored applications are blocking requests from the stations
bestg01 St. Ghislain Belgium Europe 35.233.40.54
fiham01 Hammina, Finland Finland Europe 35.228.165.156
defra05 Frankfurt, Germany Germany Europe 35.242.231.146
nleem01 Eemshaven Netherlands Europe 35.204.95.134
gblon03 London United Kingdom Europe 35.246.104.143
Checking against public available IP gelocation services they seems in USA.
Can you please confirm that those above are actually located as stated in the product ?
Release : 99.0
Component : CA APP SYNTHETIC MONITOR (WATCHMOUSE)
These stations are running on Google Cloud Platform.
The Europe locations match our listed locations
https://cloud.google.com/about/locations/?region=europe#region
As such the IP registration is to Google in Mountain View and most geolocation services will detect these are being active in US based on the SWIP (Share Whois Project) database.
However the requests will actually physically come from the stated country.
Found discussion which contains a statement on aspects of this problem from a former GCP product manager
