Does Bing fully support SNI yet?

[simon.serrano]

We're working on enabling SNI on a large number of ecommerce websites, however I've read that Bingbot has real issues with SNI.  There was a 'through-the-grapevine' response from Microsoft in April 2015 saying it was supposedly going to be fixed "within the next 6 months," but I can't find anything that corroborates that.

There was also an article on SEL in July 2015 that basically said that microsoft may have pushed a fix out, but that there were still lingering issues.

Hi Simon,

It's not looking great. I don't have any inside information from Bing / Microsoft, but there seem to be SNI pages that are still not being indexed correctly. See, for example, this page: https://www.mnot.net/blog/2014/05/09/if_you_can_read_this_youre_sniing which is nowhere to be found in Bing's index.

A site: search on bing finds two posts from the mnot site (out of hundreds). So it appears likely to still be flaky but I haven't gone down the rabbit hole of looking for other reasons that site may not be indexed, nor checked that it actually is using SNI. I also don't have an SNI site to test things on, so that's the best I have for you, I'm afraid.

The only other link I found that may be interesting is this page claiming that SNI is supported by bing: https://www.ssllabs.com/ssltest/viewClient.html?name=BingPreview&version=Jan%202015

Sorry that's not more useful.

You could reach out to the author of that SEL post (Ben Goodsell) and see if he's seen any changes since he wrote it.
