bruce was there an issue with megasearch getting headers on 4/25 ?
No, there was no problem on that date. There has never actually been a problem with MegaSearch.
bruce I'm seeing binary articles on another service that are otherwise not seen via megasearch.
MegaSearch indexes thousands of newsgroups, but not all of the 120,000+ newsgroups out there.
So it could be that the missing files come from a newsgroup that has not been indexed.
If you send me the name of the newsgroup and the filenames I will see what the reason is.
