Custom Domains and Regional Storage

Using a Custom Domain affects how regional storage works on your site.

TLS/SSL Certificate Region

If your site uses a Custom Domain name, migrating your root folder storage location also moves the SSL certificate. This causes a brief interruption to your service while the DNS change propagates. Your users may lose access to the site for approximately 15 minutes, so plan the change for an opportune time.

If you are using a Custom Domain and change the primary region where files are hosted on your Files.com site, we will issue you new IP addresses in the new region and release your old IP addresses.

Transmission Performance

Implementing a Custom Domain, along with the associated Dedicated IPs, affects the transmission speed of international file transfers.

When a Custom Domain is implemented in a different region than your storage region, the global acceleration features of regional storage are bypassed, and file transfers take longer than usual. To maintain performance, implement your Custom Domain in the same region as your storage.

For global customers, all global users are routed through the region of your Custom Domain and its Dedicated IPs. For example, if your Custom Domain is in Europe, all file transfers are routed through Europe on their way to their final destination. This also applies to transfers to your Regional Storage. If your Custom Domain is in Europe and you have a folder stored in Singapore, all file transfers to the Singapore folder travel through Europe, even when they originate from Singapore itself.

If global transmission performance is your priority, do not use a Custom Domain with regional storage.
