@Neoon Dropped you a message on Quota for my account.
Also which location has IPv4 NAT + IPV6 ?

All of them? In Europe, there's Helsinki, Sandefjord, Oradea, Vilnius, Milan, Bratislava, and Meppel. Oceania got Melbourne and Auckland. Asia has Singapore, Mumbai, Islamabad, and Mumbai. Africa only got Johannesburg, while the Americas only got Valdivia.

It might be a glitch or something, but when I tried Valdivia days ago there was no IPv6 connection, and installing anything took minutes. I just tried it again and while the dashboard says it's running, I can't SSH into it, and using the shell shows apk is locking up in the background (I picked the Alpine image which doesn't come with curl and I wanted to check for IPv6).

It works just fine in Singapore (though currently the stock is low), Mepple, Mumbai, and Johannesburg.

Neeon confirmed to me there is no Ipv6 on Helsinki. So I guess there are only few out there with IPv6.

I believe they all have IPv6 except Tokyo Equinix and Helsinki.

So I setup 2 containers now to test -
One says my SSH key is not right
Second say login via SSH key is not acceptable method... I double checked my SSH key... Seems to be correct..

Just to update downgrading from Ubuntu 24 to Ubuntu 22 made it work.

Is a known Bug if you select KVM that the ssh-key may not get installed.
I am working on a patch, in the meanwhile you can go open a Shell and copy the key over.

vilnius has issues, if I click manage

Failed to contact Node, please try again later.

and it has been doing it for 2 or 3 days...

Fixed, apparently I did not setup the cron correctly.
The monitoring didn't pick that one up, will update it.

@Neoon Something is up at Sandefjord. Check this load for idle VPS.

The Node is fine, the dedi has 4 cores, a load of 1 is just 25% load in total TM.

Mumbai is currently down, forgot to make it public visible on the status page, fixed.

Issues regarding token validation are fixed, the regex was broken, once again.

Could you enable bbr congestion control on host? It could significantly improve the speed of tcp based application include SSH. Since hosts both higher than 4.9 kernel, only 3 commands needed.

echo "net.core.default_qdisc=fq" >> /etc/sysctl.conf
echo "net.ipv4.tcp_congestion_control=bbr" >> /etc/sysctl.conf
sysctl -p

I don't see a point, most packages have a 100Mibt cap.

It's not the difference between 100M and 500M, it's the difference between usable and unusable. Especially in those exotic areas, packet loss makes SSH and other TCP based app hard to use.

You can see the chart, over 10% packet loss and 300ms in some areas for my network, recently my usual proxyjump's network has gotten worse, without a good proxyjump SSH connections to those containers are a bit torturous

I have a small 64mb instance in almost every location, never noticed lag or loss... Yes bbr can improve stability in some use cases, don't think it's needed for microlxc purpose?

VMware workstation and parallels desktop can simulate packet loss and latency. You can experience 300ms with 10% packet loss, test ssh with bbr on and off.

Yea but the thing is, did you ever reach out to me because of a location having packet loss issues, so it would make sense to apply it?

And if then, we probably have ditched that location for shit network quality.
I get the point, but I have not seen a single network report this year.

Ok... Thanks for the confirmation.
I hope it is not permanently gone & will rise back from dead.
