I am not using a VPN. Here are some ping statistics from the NUC, eu1 is around 30ms, us1 around 100ms.
I don’t see how it could be network interface, cables etc. if it only affects us1.
EDIT: It seems to have been a temporary network issue. When I look at only the last 50,000 lines of my logfile the error rate is 0 for all satellites.
