For interested, here are 3 graphs presenting the drop. For every graph
the left side is OTO#1 and the right is OTO#2. Monday morning was the

I do have a connection on OTO Plug 1 in Zürich, even with the EWZ
provided Fiber/Ethernet bridge (4 Ethernet-Ports), with one port used
for a line to Cyberlink (1 Gbit/s).
External physical systems within Switzerland are mostly 2 - 2.5 ms with
IPv4, IPv6 sometimes slightly more.
The DNS at 18.104.22.168 / 2001:4860:4860::8888 has 1.8 ms.
And the VM I have at ungleich.ch, has 4.7 ms (IPv4), and 5.2 ms (IPv6).
Almost a decade ago I had a MC2-based (copper) line with 10 Mbit/s from
Cyberlink and I do remember that for systems within Switzerland it was
also at ~3 ms.
I also have a Sunrise/UPC Cable connection with IPv4 only, there the
latency is ~21.5 ms and 25.4 ms (for the VM). But during the night
(since around end of August) it is significantly higher, sometimes even
above 50 ms. This is not the first time and it usually does improve
again after a few month, e.g. when they split the cable segment into
So for me it seems that your ISP probably has the most influence for the
latency of your line with their infrastructure and transit behind.
