In the last few days, I noticed my back office wasn't operating correctly. It was slow to load almost every page and sometimes popped up timeout errors. After debugging, I found that the Mailchimp module is the culprit. If I disable it, everything flows fine again. After opening the module config, I see it's presenting an error " Server error: `GET https://us11.api.mailchimp.com/3.0/lists` resulted in a `503 Service Unavailable` response:"
Is this happening to anyone else? Does anyone know how to resolve?
