@Gertjan said in Not sure this is normal:
stashed somewhere in an obscure registry key
Not sure I would call obscure
Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\Config
That's expected behavior on AWS when the CPU is maxed. See https://docs.netgate.com/pfsense/en/latest/solutions/aws-vpn-appliance/instance-type-and-sizing.html
You'll need to find the cause of the core maxing out.

Thx, had he same problem, for example with www.daiichisankyo.com (which resolves to part-0032.t-0009.t-msedge.net - 2620:1ec:46::60)
Setting the MSS to 1452, resolves this issues... And yes, it does not feel quite right. :-/
