Yes, but the sooner you catch it, the better.
If the domain name expired a few days ago, you can simply renew it (ask for help if needed) and your site will be restored almost instantly.
If it expired within the past few weeks, you can probably still renew it but you may need to pay a “reinstatement” fee. The reinstatement fee is required by law – we did not create it and we cannot waive it.
If your domain has completely expired, most likely it is gone forever (someone else may have purchased it). But it’s still worth checking, so ask your web consultant and we will see if anything can be done. Yes, there is a process for buying domains from other people, or at auction, but this is rare and expensive. Avoid this situation if you can.
In the future, do everything possible to stay on top of your domain renewal dates. It is one of the most important things you can keep track of in your business.
