When a website or mail go down, it gives prospects pause as to how reliable you are. Assuring them their information you hold is safe, your services are reliable, and that you always have a back-up plan in place will allow them to relax, trust you, and recommend you to their colleagues, friends, and clients. Sometimes your website is the first place they try to get to know you, then they move on to your social media presence. How are you looking? How current is your site? Links all working? Content up to date? Contact page cryptic or straightforward?
