@Keith Fetterman it might have to be related with NetSuite servers serving .avif images now. That’s where your research should focus.

NetSuite servers are not serving the new image file formats, the caching service is. If they have disabled the NetSuite CDN caching service, this shouldn't be the cause.

@Steve Goldberg, I checked with LFS, the owner of the Go2marine SCA website. They are only serving JPEG and PNG files. They are not using a new image file format. What is strange is the files appear in some regions and not others. In the ones where the images are not appearing, NetSuite servers are returning server reject errors or server not available.

They are only serving JPEG and PNG files. They are not using a new image file format.

Again, it's not a NetSuite thing - it's a caching service thing. It doesn't matter if the source file is JPG or PNG, the caching service is configured to convert old image formats to newer ones if it would result in better performance. Anyway - I am assuming that in order to get this third-party caching setup to work, you've disabled CDN caching on the site by unchecking the checkbox in NetSuite?

@Steve Goldberg Correct. We’ve been using Layer0 (3rd party caching service) with Go2marine SCA website for two years without issue until around mid August. The “Use CDN Cache” checkbox on the Domain record is unchecked. The last time SCA code was deployed to NetSuite servers was June 5, 2024. We didn’t start experiencing issues with the NetSuite servers until Mid August. Something changed at NetSuite around that time that is causing the 503 or 531 errors when requesting images. When you say it’s a caching service thing, are you saying that if a client requests a JPG image from an SCA website, the Akamai caching service will return the image as an AVIF image instead of a JPG image?

I am, yes.

Old thread, I know -- but I've had massive issues with Google not able to crawl my JPG images. Turns out.... none of my NetSuite hosted JPG files are actually JPG files. They're all AVIF now. I get that this is a product of their CDN caching system. But I use SiteBuilder and don't even have settings to turn off CDN caching. Browsers and crawlers are requesting images with a .jpg file extension, but the file returned is avif. Browsers don't seem to have a problem with it, but Google did, which lead to major issues with Google Merchant Center and Google Ads. Also, when a viewer on our website tries to right click "Save As" on an image, they can't save out to a JPG anymore, only AZIF. It's pretty shocking that NetSuite didn't alert customers ahead of this change. I'm not anti-AZIF, but that's huge change to just slide in on their server/hosting setup. They've made so many changes like this in 2024, my head never stops spinning. I can't be the only person who's been chasing image problems like this....

Sorry to hear that. It's kinda weird that that happens. Google Search made the announcement in August that they support AVIF, but I can see that Google Merchant Center doesn't list AVIF as a supported type. How have you resolved this?

Thanks Steve. Appreciate that info! I have stabilized my situation.... I'm using feed rules in Google to essentially text-replace the .jpg and .png to .avif. And Google seems AOK with that. My worry is if NetSuite makes any changes it'll send my products back to the penalty box pretty quickly. I communicated with Google on this matter, and they said the same as you found -- that Google (officially) doesn't support AVIF in Google Merchant Center... but it seems like they do, despite saying that. So I'm going to roll with it. Thanks again! You always have helpful insight for the group.
