I just increased mine to the max of 10 years, I guess I should have done that anyway just for security. What happens though if namecheap goes out of business during that?
.COM agreement between registrars and ICANN requires registrars to regularily store all registrant contact infos in IronMountain and set ICANN as escrow, therefore allowing ICANN to contact all registrants should a registrar fold and allow them to transfer to another registrar. Another reason to keep the domain ownership informations up-to-date. [1]
