T has a much longer history of dividends than IRM. While that definitely doesn't guarantee it in the future it is an indication that the company has been able to consistently grow over the past 50 years. I've looked at the debt load of T, and unless there is a recession or something similar I think they should be able to continue paying out their dividend.
