Ok, I could not find any of your public IP addresses in our block list but I did the requests from your site admin in our logs. They all received a 200 (OK) status response which does not explain the “Service Unavailable or Too many request” your are getting from your admin… In short: I cannot explain the error :/
Please download the latest version from your account page https://premium.status301.com/account/ (Downloads tab) and install that zip through the admin Plugins > Add new > Upload as a new plugin. You’ll get the choice to update the existing but older version, answer Yes 🙂
Our apologies for the inconvenience. Please let us know if this happens again at the next update!
