Some tests appear to be flaky due to network issues connecting to worldbank.org, e.g.:

ERROR message_ix_models/tests/tools/test_wb.py::test_get_income_group_codelist - requests.exceptions.ConnectionError: HTTPSConnectionPool(host='datacatalogfiles.worldbank.org', port=443): Max retries exceeded with url: /ddh-published/0037712/DR0090755/CLASS.xlsx (Caused by NewConnectionError('<urllib3.connection.HTTPSConnection object at 0x7f7d9b898190>: Failed to establish a new connection: [Errno 101] Network is unreachable'))

These could be resolved by:

• Marking the tests as XFAIL and/or flaky. I think the latter may not help, since when the server is not responding, retries with pauses of a few seconds will not succeed after an initial failure.
• Storing a mirror of the file in a more reliable location, e.g. on Zenodo or in this repo.

For now, I am repeatedly re-running jobs until they pass.
