How Do You Find Anything and Everything on the Internet?

[zero_day@sh.itjust.works]

Tell me about your methods and sites for finding anything and everything you look for on the internet. Information, normal day-to-day searches, investigation, research, NSFW, gore—anything and everything. Be as detailed as possible.

Also, when a site you normally use goes down or becomes unavailable, what do you do next to fulfill your needs in that area? What alternative sites, tools, or methods do you use, and how do you go about finding them?
