Is down?

I am trying to run the qubesos system update command:

$ sudo qubesctl --show-output state.sls update.qubes-dom0 && sudo qubesctl --show-output --skip-dom0 --templates state.sls update.qubes-vm

However, I have been getting the following error for the couple of times I tried in the past hour:

Error: Failed to download metadata for repo 'qubes-dom0-current': Cannot prepare internal mirrorlist: Curl error (6): Couldn't resolve host name for [Could not resolve host:]

I have setup my QubesOS so that the updates occur over Tor network using the sys-whonix disposable qube.

I have tried getting a new circuit using the sys-whonix GUI but the same error persists.

Is there a problem with the server?

I retried the updating command and it went through this time. It had a bunch of updates to dom0 packages. I guess the slow internet speed caused connection drops before.
