Both candidates for the presidency of the United States have websites. So who provides web hosting for each of the major candidates?
HillaryClinton.com is hosted by Amazon Web Services. HillaryClinton.com is primarily using Google’s Gmail service for handling email. HillaryClinton.com is also using other email providers to help handle email and delivery of emails.
DonaldJTrump.com is using CloudFlare as a proxy (between end users and the real web host) so it is not possible to detect who is actually providing the web hosting service to the site. DonaldJTrump.com looks like it using Outlook.com as a part the email handling. Other companies are also used in handling the delivery of emails for DonaldJTrump.com.
