My site has many modules which are indexed by google.
Recently there has been a database problem so the site was not appearing well like many links returned 404 i think.
Now i have make it working and all the content what previously google indexed are as it were.
How do we update google that i have corrected and the pages which sent 404 are not 200?
That is now i wanted to tell google that the urls which sent 404 are now working fine so that google will update it soon before it removes from its database.
