Hello there! We are starting to use Google PageSpeed Service (the CDN proxy service, working exactly like Incapsula or Cloudflare) for a network of 70 websites. For now we have one IP by website and we try to make each website looks independent for SEO purpose. Our worry is if we move the 70 websites to Google PageSpeed Service, they will share the same group of IPs and the Google crawler will detect that. Is it a rightful concern? Thanks!
