Hi all,
I'm having a hard time with my UPC Internet at home. Connections to f.e. Github are nearly impossible since a few weeks (can't remember exactly since when =( ), but when connecting through a VPN (exits at AS57118) there are no performance issues other connection problems. This connection troubles are not only to Github, but also to other random destinations like Ifolor, sometimes Google, sometimes SRF, ... I couldn't find patterns at the moment, SmokePing started collecting them for me =) (currently it shows huge paketloss, but still have to wait some more days for better graphs).
Is anyone else having such issues with UPC home Internet?
Cheers, Tobias

Hi all,
Hallo!

I cannot recall when was the last time I had performance issues with my UPC Internet connection.
CU, Venty
In the last years I always had performance issues to some destinations... If I could, I would change immediately to any other ISP, but unfortunately there are no alternatives here.
Freundliche Grüsse Matias Meier

That's on my todo list for later this year. Sadly no fibre available here, so no Fiber7. Currently investigating the best alternatives, probably Monzoon with their nice VDSL connection offer (https://dsl.monzoon.net/) incl. static IPv4 and native IPv6 could be the solution.
Nevertheless, I'm curious what happened to my UPC connection and try to find out what I can do here and at best fix it.
There is a small possibility that you have a hardware problem.
10 years ago I bought a DECT telephone that interfered with my cable modem if the base station was placed within 50cm of the modem. Got up to 8% packet loss when testing with "ping -f" to the gateway IP.
Simply moving the base station to the other side of my desk fixed the problem.
Did you recently buy something that emits a lot of radio waves? Do you frequently pose your mobile phone near your modem?

Hello, Last week i have had after 1 till 2 hours breaks during downloads. No Server give during 10 Sek. an answer. After this time it works normal for 1 or 2 hour. We are using a horizon.

Hi Tobias,
well, I have seen by lots of customers in area ZH Altstetten, ZH Uni and ZH Seefeld in last weeks multiple interrupts as well as IP changes. Normally they change quite rarely. So they may change something in their network.
In general I have good performance with UPC. simply with some prefixes upc is still having problems, may with some upper tier carriers, or whatever - routing is often terrible.... and only via UPC.
most affected are prefixes located in UK. brexit ?-))
e.g. all my tested ISPs have not this issue, but cablecom:
- IaaS provider, 2 prefixes to same datacenter/servers - prefix A fine (8 hops - 1 hop rfc1918 at cablecom), prefix B goes via USA and back (17 hops - 1 @ccom).
- due to my tests it is not a routing issie by my IaaS provider, simply cablecom goes a complete wired path... - roundtrip time + > 100ms in case B
- e.g. via sunrise(home) it works fine (9 hops - and 3 are RFC1918 at sunrise... wtf...) - 5 hops / from nine via swissix to A and B :)
and general: if you have these black actual cablecom modems, or older ones - a reboot once a month helps..... why ever this device lames with higher uptimes. horizon was simply a mess....
Cheers Stephan

Hi Stephan

I'm in luck and have a classic Ubee modem, no UPC router or Horizon box. Reboot didn't help, was exactly the first thing I did when the connection troubles started to show up. I even rebootet my pfSense APU, upgraded to the latest version, run diagnostics, etc. There is still a small possibility that my router does something strange here, I guess I'll do some tests using a spare EdgeRouter laying around. And there is hope that the Turris Omnia Router will ship soon =)
Cheers, Tobias
My guess is, UPC just has the occasional overbooked peering link problem. A while ago I was frequently watching youtube videos, and found the quality to drop considerably in the early evening hours, when probably many other customers also started to watch youtube. Enabling a VPN to the UK, sometimes even to the US, brought back the quality. So, in my interpretation, my home connection was NOT the culprit, but the backbone interconnection of UPC with the peers I was watching content from.
I haven't had such frequent issues recently, but then I also mostly switched to watching twitch instead of youtube, and that will go over different peering links.
Cheers, Markus

No, not really. The modem is far away from mobile phones or even from the DECT station. I fear that it's not a modem problem, more a routing problem. When I connect to IPs which are bad in connectivity through my VPN rather than directly, all is good. I don't think the modem has a problem here (Layer 2 bridge doesn't do routing).
