Where should I host a website for South American visitors?
The short answer
São Paulo is one option to test, including for Amazon Lightsail, which added the region in June 2026. Compare it with other suitable locations from your actual target countries; no single region is fastest for all of South America.
In more detail
Map your audience by country and city before selecting a region. A website focused on Brazil may have different network needs from one serving Chile, Argentina or several countries. Use that audience mix to build a shortlist.
Amazon announced Lightsail availability in São Paulo on June 12, 2026. This makes it a relevant Lightsail option for regional testing. Confirm the required services, capacity and current pricing for the specific configuration you intend to use.
Test the same pages from your audience’s networks, comparing response times, failed requests and busy-hour consistency. Include another location, such as a suitable US region, if it fits your budget and service needs. Choose from the observed results rather than assuming a location is faster solely because it is on the same continent.
