Mamba hangs for long while before loading package records
Hi,
When I use Mamba on a company server, I notice it hangs for a long while before it even starts looking through repos. It could be that my company blocks some outbound requests, but I see no mention of this in the logs.
This is the relevant output of mamba install -vvv <some random package>, piped to a script that adds timestamps.

This is very consistent and happens irregardless of the environment that I'm in. Pretty sure it's no resource limitation, as the system has NVME drives and plenty of (unused) cores and RAM. This also happens in the latest version of Mamba:
mamba 0.21.0
conda 4.11.0
I can of course provide additional information if required
Not as far as I can see. The "first" two files differ depending on the environment I'm in and it happens across environments. The second two files only differ between envs in their filepaths and the sha256_in_prefix field in their contents. I have attached the contents of a libopus-1.3.1-h7f98852_1.json file below.
This is, for example, the output of running an install command in my base env:
