Please see image below. As of today I can no longer see the version number displayed under the download options. I used to check to see if there were any newer versions as the releases page is not having the daily revisions. I notice that we are often asked like in another post today by @lubos to e.g. download version 21.3.48 The last one that was visible was 21.3.47. So please re-enable as it will help to know which version is the latest. Thank you.
Sometimes it takes a little while to rebuild the web site. The version 21.3.48 shows now.
Happy it is back whatever caused it. Most of today it did not show any version. I just decided to create a post before going to sleep when noticing it still was not re-appearing. It seems by co-incidence that they have appeared just after my post. Guess I should have waited some more. 
Or, you might have attracted attention. Who knows? I only know I once reported the same phenomenon and got the answer I gave you.
Thought that it could be one of the unsolved mysteries of King Tut’s tomb
