We are aware that the Wolfram Alpha Skill is currently not responding to queries.
Our API key has been blocked and we’re reaching out to get it back online. This means that Mycroft may not have answers to everything that it can usually respond to, particularly general knowledge questions.
This should be a quick resolution once we’re able to get through to the Wolfram team so I don’t anticipate this to be a long outage.
Will post again once we have more details.
