For years, the link associated with this event has pointed to a page at AT&T describing the first mobile telephone call. On 17 July 2016, while checking the link, it was discovered the page is no longer there - the link ends now up at some generic AT&T "Innovation Labs" page that has no useful search functions: Searching for the missing page yields 1251 results, and none of those examined appears to be in any way related. Thus AT&T's Web site is no longer a useful source of historical information.

Further exacerbating the problem, the "Contact Us" links on AT&T's Web site only provide links to "customer support" - if you're not a customer, apparently AT&T thinks you have no business contacting them. This makes it effectively impossible to contact their webmaster, or anyone else who might be responsible for providing continuity with the past. (In fact, using their "Search" function with the query "contact webmaster" turns up zero pages - the page says "Hmmm....looks like we don't have any results for contact webmaster" - not very useful.)

It looks like AT&T has decided to follow Yahoo's example and become an unreachable company. Good luck with that...
