ANSWERED Swiss Servers always disconnects and packet loss?

[Gandalf15 0]

I always used a UK Server until it shut down. I then decided to switch to a swiss server. I used Athebyne and Toliman. I realized they are very unstable - my client lost connection all the time (my ping to the swiss server is 10ms). I realized they have several times an hour problems with packet loss:



Is this Problem now to AirVPN? It seems also - at least for my case - it they are unusable like they are. I mean all 10 minutes I get disconnected.

What is going on there?

I now switched to a DE server - so far it works.

Hello!

A few flood attacks caused various problems throughout August but the main problem since one or two weeks ago is the uplink capacity in our opinion.
We were expecting maintenance operation in the Zurich DC to increase uplink capacity and improve access switch redundancy by adding a second switch to the rack between Aug 31 and Sep 1, but it was unfortunately re-scheduled to Sep 8. We will evaluate whether the added capacity will be enough to resolve the problems and we will act accordingly.

Kind regards

Thank you for that reply!

I will wait then and see if its worth to switch back!

Hello!

Any problem related to IPv4 seems resolved. IPv6 related problems persist. The warning on packet loss you can see on the servers monitor is caused by IPv6 related problems: intermittent but very frequent packet loss. These problems do not affect Athebyne, Dorado and Toliman. We are in touch with the dc engineers while investigating this problem.

Kind regards

Hello!

The problem with IPv6 has been almost resolved through a switch replacement. However, a moderate packet loss on ICMPv6 traffic persist, up to 2.5% as far as we can see. Datacenter technicians are still investigating but according to our tests all the Swiss servers are perfectly usable with IPv6 too, currently: TCPv6 records negligible packet loss / re-transmission < 0.5%

Kind regards
