Your tests timed out. This might mean that there was an issue in our infrastructure, but more likely it suggests that your code is running slowly. Is there an infinite loop or something similar?
Please check your code, and if nothing seems to be wrong, try running the tests again.
@glennj – Yes, since Python 3.7, Python dicts are guaranteed to preserve insertion order, and view objects (dict.keys(), dict.items()) as well as list(dict) will return keys (and (key, value) tuples) in insertion order.
There are some infrastructure issues (related to Denial of Service attacks) and the site is under heavy load. This is likely the cause and not your code.
