Hi Dave,

Thank you for your fast reply and your recommendation.

I was checking our weekly Wordfence report after I have posted that. I was looking for IP addresses from Switzerland (because it looks odd to me to have blocked IP addresses from Switzerland while other countries such China, India etc. are usual). And there were more such entries. Most block counts last week had the IP address from my host, but there were others:

#1 2a00:d70:0:b:2002:0:d91a:3755 // Switzerland // 979
#2 45.55.41.191 // United States // 60
#3 120.27.6.97 // China // 21
#4 2a02:1206:458a:3d40:106b:69f8:11d7:f21a // Switzerland // 11
#5 2a02:120b:7fc:ff50:56d:9d09:65d4:2de5 // Switzerland // 8
#6 2400:6180:0:d1::827:1001 // Singapore // 7
#7 2400:6180:100:d0::19f8:2001 // India // 6
#8 2001:8d8:965:2be5:a330:d16d:4548:0 // Germany // 6
#9 2a02:120b:2c69:aed0:5cf1:8abb:6513:d7be // Switzerland // 6
#10 2a03:b0c0:1:e0::4dc:a001 // United Kingdom // 6

Filtering the IP addresses in Live Traffic Advanced Filters, most wordfence_syncAttackData and wp-cron.php were from IP #1 (as in my preview post), #4 showed no result #5 and #9 showed the following results:

Stans, Switzerland left https://mydomain/kontakt/ and was blocked for UA/Referrer/IP Range not allowed at https://mydomain/?wordfence_syncAttackData=1568230128.9357

At the moment, Live traffic is showing wordfence_syncAttackData and wp-cron.php every view seconds from IP #1, http response is 503.

I am not sure by whitelisting our host IP. Is there an attack ongoing or what do you think?

Thank you for coming back to me.
