Does someone else also consider heavily Performance issues with POP chgva01? I recognized this the first time yesterday (15.04.2014). I can't see any Troubles within the sixxs.net Homepage or the traffic stats of this POP. thanks for answers :)

You might want to consult the FAQ and actually provide details, instead of making a statement without detail.

That's why I wrote this post rather than a Ticket to get msgs from others, if they experiencing the same. My Internet connectivity with my IPv4 carries works perfectly. Here are the results from the Speed test recommended on the FAQ (Values are in Mbit/s: Netherlands, ZeelandNet IPv4: 17.1 IPv6 10.2 Lyon, LaFibre.info: IPv4: 19.8 IPv6: 19.4 Roubaix, OVH: IPv4: 19.9 IPv6: 18.8 Bucharest, RCS&RDS: IPv4: 20.0 IPv6: 15.7 And a speedtest with Hongkong (from speedtest6.com: Download Speed: 4.31 Upload Speed: 0.3 Connections to Google Services (YouTube included) or Facebook is quite not possible since yesterday. When I disable the IPv6 connectivity on a specific Computer, Internet Access works like a charm. Please tell me if I can help out with more Information.

As the IPv4 and IPv6 values are almost the same, what is the problem?
Connections to Google Services (YouTube included) or Facebook is quite not possible since yesterday.
Did you see the FAQ item mentioned above? Did you notice the "include a sufficient description as mentioned in the Reporting Problems section of the contact page" mentioned in the two big boxes when posting? Please provide a lot more detail. Stating "this and that is not possible" without any actual details does not allow for seeing what the problem might be, and as the FAQ alludes to, there can be many many issues. Hence, details please!

As per the FAQ mentioned above, ever considered the path it is happening over? Really, there is nothing bad about that. As is clearly shown (by yourself) other services are fine.
http://stage.results.speedtest.comcast.net/result/482746784.png
Comcast speed test is meant for Comcast customers, they do not serve well outside of that. They are also on the other side of the planet. I can do close to 250mbit to most local servers, but to the Comcast speedtest only get 22mbit, both IPv4 and IPv6 mind you. The path is the important part here. There is a reason why we have a FAQ related to speed.

What are the paths for each of these?
I really don't know how to provide better Information, please tell me, what I can do, or what Kind of Information is helping.
There is a number of things mentioned in the FAQ, there are others on the Contact page, as pointed out to you several times already...

Your first hop is already 66ms, that is quite a big part of your latency. and a traceroute (IPv4 mind you) shows why that is so much:

Wow, going over Moscow... that is rather bad. I'll contact IP-Max to ask if they can peek into that.

And it is not strange that it is going there, seems Swisscom is forgetting to route it properly: https://stat.ripe.net/84.253.0.0%2F19#tabId=routing Which might explain why you experience such bad connectivity as quite large parts of the world do not even see the prefix you are coming from.

Thanks for the link. So, my understanding is: My IPv4 Connection works perfect, because everyone has announced their routes OK. But the IPv6 tunnel is etablished from chgva01 to my tunnel endpoint. Because of your Investigations of a bad Routing by swisscom, the tunnel is routed over moscow. And finally this is why the Performance is bad? If this is true, I then will call the swisscom Support.

No, your IPv4 connection can not work perfectly, because Swisscom is not announcing your prefix properly. (There is a /19 + /18 being announced, but the /19 is more-specific and thus the /18 gets ignored)
Because of your Investigations of a bad Routing by swisscom, the tunnel is routed over moscow.
Not because of our "Investigations" is the routing bad, it simply is bad because they announce it wrong. And as they announce it wrongly, there are only a few paths, and one of those paths leads over Moscow.
And finally this is why the Performance is bad?
Yep, routing your packets half-way around the world causes bad performance, compared to proper routing :)
If this is true, I then will call the swisscom Support.
Do call them and point them to the RIPE URL mentioned above and point out that the /18 still exists (which is bad), while the /19 is properly announced (which would be the good one). They should be aware though, as I spammed SwiNOG with this tidbit which should actually reach the proper people at Swisscom instead of their support department (then again, Swisscom has proper support folks from the few times I contacted them, not using them for a long time though...)

Well ok, the clouds are going away :) Thanks for pointing that out. My Statement was unclear. My experience of the IPv4 Connection was good, but I obviously only used some services, and not the hole Internet. Important inofmration, the the /18 will be ignored, thanks for pointing that out!

I have called them now, and they are looking for the issue. I have always made good experiences with swisscom Support, they always try to help you out. They will give me a call later.

Until now, I have already learned a lot. But I've got now one big question, and I hope you will find the time to answer :) Your tracert to my tunnel endpoint 84.253.1.161 goes over moscow. When I do the same to "your" geneva tunnel endpoint:

Everything is fine from my Point of view. My understanding is, that the package which i'm sending is going directly through the correct route. But the reply from the router can go through russia because of the routing. So shouldn't be at least the latency as much high as in your Tracert? Or follows the reply package from the target host the same route as the request was coming? I can't Image this, but I'm really no longer sure about. Thank you very much for your time!

That is because IP-max is discarding (and thus ignoring) the /19 announcement, hence the /18 is chosen which is going over NTT and is much speedier. Now to see when Swisscom solves the problem for the rest of the world. Note btw: that a traceroute is one-direction. The forward and reverse path can differ significantly.
