Extremely Slow Download of Updates

Hello there! I'm having the same problem right now. It says that upgrade will take 3 days. I upgraded yesterday on another machine and was very fast. Maybe we have problems with the upgrade servers today?
 
which CDN node are you connecting to?
 
That node did not seem all to overloaded, albeit there was some higher base traffic – that said North America is definitively a region where we'll look into adding more CDN nodes this year.
 
I'm encountering the same issue today:

Code:
# pveam download local debian-13-standard_13.1-2_amd64.tar.zst

Currently (& over the last number of hours) it seems the Proxmox update servers (download.proxmox.com) are dribbling data:
Code:
42% [1 pve-qemu-kvm 17.7 MB/32.1 MB 55%]                 2,467 B/s 3h 29min 58s

General internet on my end, pretty alright/usual.
Anyone else experiencing this?
 
which CDN node are you connected to?
 
could you also tell us where you are located (and possibly your ISP? :)) - or rather, where the machine you are experiencing this one is and how it is connected ;)
 
could you also tell us where you are located (and possibly your ISP? :))
If you feel that is absolutely necessary towards solving the issue, I could DM/PM that to you personally.


Currently:
Code:
55% [1 pve-qemu-kvm 25.6 MB/32.1 MB 80%]                  6,281 B/s 1h 1min 31s
I believe the average in the last few minutes is more like ~5,000 B/s average. So better than 1 hour ago.

I did some speed tests that appear regular for my connection.
 
We had one of our CDN nodes running in the APAC region hit some unexpected traffic limitations, while we're waiting to get that lifted we downgraded that nodes weight in the traffic distribution significantly to prefer other nodes in that region.
 
CDN nodes running in the APAC region
I should be covered in the EMEA region.

However, a lookup (Google) of that above posted IP 117.120.5.231 shows:
Code:
The IP address 117.120.5.231 is located in China and is associated with the organization CNC Group (China Netcom)
That looks interesting/worrying?

Thanks also to you for your swift reply.

This is the APAC CDN node I talked about. Maybe the geolocation of your IP is outdated in the geoip DB we use, you could submit a correction request at the source of that:

My upgrade finally finished (some time ago) - so I'll leave it for now, since apart from the OP & this current instance, I've had no issues.

Thanks to all the caring staff.
