Does the bad gateway messages that we have been receiving lately impact google search results? Like, when a google bot goes to index of our images and the image is not found, did we just lose that image from the google search results or the other search engines?
I just can talk from experience with my own site, John.
The server my site is hosted at was down for almost a month with 502 (hardware failed) and it did not have any impact on my google rankings or the google search results for my site.
When the server was up again I resubmitted my site to make sure Google starts visiting again (if it ever stopped).
