Versione TLDR
The is.gd domain has been put in a serverHold status by the .GD registry
Perciò se la situazione verrà sbloccata tutto tornerà online, quantomeno non è un’improvvisa decisione di spegnimento volontaria.
We apologize for the inconvenience this has caused you. The is.gd domain has been put in a serverHold status by the .GD registry. We've tried contacting them and our domain registrar by phone, email and their ticket system to resolve the issue, but it goes to voicemail or has not been responded to by them yet.
We think the likely cause is because of spam or other abuse that is very common with URL shortening services, but obviously have not received an official response yet to know the cause. We have no reason to believe that we can't get the site back online.
While we can't do much about your existing links until the domain status is resolved, we recommend you use TinyURL.com for now for your URL shortening. They are a well established brand and domain that I know is on top of abuse issues and not likely to be have issues."
