Description

Hello Admin Team,

Since the 5th or 6th of January, we have been facing extremely poor network
throughput when using the OBS Interconnect on our private OBS instance. We have
configured OBS interconnect for both openSUSE.org (api.opensuse.org) and SEBS
(api.suse.com) instance. The maximum speed that we get is approximately 50 kbps!

I would like to present some data before continuing further. This is what we get
on our backend server:

# curl 'https://api.opensuse.org/public/build/SUSE:SLE-15:Update/pool/x86_64/_repository?view=cache' > /dev/null
% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed
100 14.5M 0 14.5M 0 0 33723 0 --:--:-- 0:07:31 --:--:-- 97338

7 minutes 31 seconds to download 14.5MB of data.

The same situation is with api.suse.com as well:

# curl 'https://srinidhi:XXXX@api.suse.com/build/SUSE:SLE-12-SP0:Update/standard/x86_64/_repository?view=cache' > /dev/null
% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed
100 12.1M 0 12.1M 0 0 30295 0 --:--:-- 0:07:01 --:--:-- 40555

Similar average download speed for both the servers.

Because of this slow network throughput, our private OBS instance is completely
unresponsive for most part of the day. This is causing a huge loss of
productivity to our teams and the product.

We have reason to believe that our external IPv4 address (192.31.114.0/24) is
being rate limited at {open,}SUSE side. There are two main reasons for this:

We are able to access api.opensuse.org at high speed

  1. over IPv6
  2. from Provo (US) and other geographies

Could you please check this on your end and help us resolve this issue? Please
let us know if you need any additional information from us.

Regards,
Srinidhi.
