Hmm, now that I rechecked my cron job I think BPS is perfectly right. Here is the URL from the cron-job: http://my.domain/wp-cron.php?1234567890987654321&action=wysija_cron&process=all
The funky thing is that the id after the ‘?’ is identical to the one in my cron job. The only difference is the ‘silent=1′ part. The full IPv6 ip is 2600:3c03::f03c:91ff:fe6e:bde4. This is from looking up that IP:

I am worried now – maybe someone broke into my system?
