Website not accessible in India

SendGB.com site has not been accessible from India for approximately 20 days. SendGB.com site is accessed from outside India. Additionally, users in India access the site via VPN. When we tested with a few users in India, we found that they could not access the site when they typed sendgb.com in the browser, but they could access the site when they typed www.sendgb.com. Could Cloudflare be a problem on the India side?
