I have a number of sites on your Enterprise versions.
I noted on Saturday that all pages are now being indexed again meaning the "%"-sign is everywhere. I hope this is a temporary error as I have spent a number of weeks a few months back to ensure all pages are translated for Google.
If all pages need to be translated again today for some reason, then Google will definitely penalise all my websites as most of the pages contain % signs and are now back to English. This is an urgent matter as it will result in loss of income, and I hope you can address this issue for the cache not working, and ensuring the previous cache is online again.
