BingBot As GoogleBot? Maybe, If It Crawls Google's PageSpeed Tool

The question was brought up at Stack Exchange:

As it shows, user-agent shows it is bingbot. But whois data of IP address( and shows it is from google servers.

So is it Google,Bing or any other content scrappers?

John Mueller of Google responded saying both! It was BingBot crawling a URL through Google's PageSpeed tool. John explained:

I double-checked with the team about these requests, and they appear to be for the PageSpeed service, which can act as a cache/proxy for websites. If search engines - like Bing or Google - crawl URLs like that, the service will forward those requests to your website when needed. That can make it look like these requests are coming from Google IP addresses, even though they initially originated elsewhere.

Pretty neat!
