In general, websites are hosted in data centers, which are the physical facilities in which the host server is located.
Your website at SiteGround will be hosted in one of the data centers on our globally distributed infrastructure. Currently, SiteGround uses 11 data centers on 4 continents, including Ashburn (Virginia, US), Council Bluffs (Iowa, US), Dallas (Texas, US), Los Angeles (California, US), London (UK), Madrid (Spain), Eemshaven (Netherlands), Frankfurt (Germany), Paris (France), Sydney (Australia), Singapore (Singapore). These have been chosen after careful consideration, as they have proven to be among the most reliable ones.
SiteGround clients are free to choose a data center location from the ones listed above for their websites. They can also change their data center location anytime from their Client Area. To help you choose the right data center for your website, keep in mind that the closer your data center is to your website’s visitors, the faster the loading speed of your web pages will be.
