Old links no longer work
Links of an older format, example https://www-bd.fnal.gov/Elog/?entryIDs=81600 , no longer work. Manually changing the link in the address bar to a currently accepted format https://www-bd.fnal.gov/Elog/?orentryID=81600 directs to the desired page. However, years of old links in the old format don't seem to work anymore. For example, the link in this entry, the source of the first link: https://www-bd.fnal.gov/Elog/?orEntryId=85010 They just redirect to the current Elog, without any error message.
I noticed this a little while ago, but I'm not sure how far back it goes--maybe the last big update, maybe a more recent one.
