We are currently looking into an issue that is preventing some users from opening some Checklists created after 1pm EST. We will update this incident as soon as we have more information. Thank you for your patience.
We monitor our systems by performing live email and web page tests constantly. Additionally, we measure the response time of the Litmus application and our Email Analytics platform from different locations.
