Since upgrading to the then latest version on 27th December, we’ve noticed that all visitors now show no ISP name.
On the same day, we can see that the “Visits Over Time” also dropped off to zero.
However, “Evolution of page performance metrics” under the performance option started recording data on the same day.
I’ve checked out https://matomo.org/faq/general/faq_52/ but our PHP configuration didn’t change on this date, only the upgrade of the software (Matomo).
We have Maxmind GeoIP enabled and as far as we can see, it is pickup up location and when we do the ISP check in the GeoIP admin area, it has this set correctly.
All sites within the Matomo installation all see the loss of ISP name on the same date as well as the other stats (loss of VoT and gain of Performance data).
Would be nice to get the ISP name back if any one has any ideas and also to clarify if the VoT is a stat no longer populated due to the gain of performance data.
