A visit to www.regions.com yields a generic web page with branding for Network Solutions, a domain-hosting service (see image, right). Attempts to access the website from several different computers in locations across the U.S. yielded mixed results, according to an informal survey conducted by AL.com.

The generic site that appeared for several users suggests that Regions may be having an issue with renewing its domain, a crucial step for keeping a website online continuously.

Comments posted by Regions Bank's Facebook account to its own page acknowledged issues with online banking. Regions Bank spokesperson Evelyn Mitchell said via email, "We are experiencing an intermittent network issue that is impacting some customers' ability to access our web site. We are working to resolve this issue quickly and apologize to our customers."
