Agreed we should be showing something for all these errors if no data is returned. The last thing we want is a blank page. The user won't know if it's Chrome that's broken or the site.  

Yes, I agree. Is there anything needed from us?

This issue has been Available for over a year. If it's no longer important or seems unlikely to be fixed, please consider closing it out. If it is important, please re-triage the issue.

Sorry for the inconvenience if the bug really should have been left as Available. If you change it back, also remove the "Hotlist-Recharge-Cold" label.

Any plans to move forward on this?

Not to the extent of my knowledge.

Er - UXer question. What do we need to move forward here? 

We either need to add error strings to "LocalizedErrorMap http_error_options" or add a fallback case to LookupErrorMap() for HTTP status codes.  It's purely UI work.  All the code to hook it up is already in place.

That's good to know! 

Edward - can you help me with figuring out what's needed here exactly? I'm sure we can offer string suggestions fairly easily. :)

(Punting out of network bug triager's queue)

Rachel, we just need to decide on the strings for heading and summary paragraph we want to show for these types of errors.

4xx errors - Errors caused by the client.
5xx errors - Server errors where the server failed to fulfill an apparently valid request

You can see the type of errors in each category here:
https://en.wikipedia.org/wiki/List_of_HTTP_status_codes

We can sync off bug to figure out some wording.

Show generic network error interstitial for 4xx / 5xx errors that do not
have any content

Currently only a small subset of 4xx and 5xx HTTP errors show a net error
interstitial when the server responds with no content. This CL adds 
generic messaging for the other cases.
