All photos missing from a 1-month span?

Are you using just one iOS device? Were there any interruptions in the usage of the device, like a phone being repaired? I know that the uploading to the iCloud Photo Library can be interrupted by having no WiFi connection. I’m not sure if it’s possible to upload with just the cellular connection.

It’s technically possible to have gaps in the pictures, if different devices are used and/or there are interruptions in the usage of just one iOS device.

I run a DropBox backup, in addition to using my iCloud Photo Library, just to be on the safe side.

Well, if it’s just one device, and there have been no interruptions or repairs (and no deleting of the device and re-installing) and it has access to WiFi everyday (I assume at home and overnight) ... then that really should not happen.

I happen to have a kid at home who likes to delete photos, so I have to keep restoring the photos he deletes. Fortunately he hasn’t figured out how to delete from the deleted folder. That’s another reason for me having DropBox.

I mention that because it might be possible that someone else deleted a block of files. I’m in the habit, now, of always checking the deleted folder, but before I did, it would have been possible for something to have been deleted and I would not have noticed it.

if you view the photos by the date option (the icon on the bottom left), it’s possible there to delete a block of photos with just one click. So, the only other thing I would think of ... is that someone deleted a block of photos and you didn’t notice at the time.

Other than that, I really haven’t heard of things going bad, like that, with iCloud Photo Library. But I’m still going to run DropBox, ‘just in case’ ... 👍
