How often is Linkscape and Open Site Explorer updated?

[ydop]

I ran a report on a URL that needed external links updated several weeks ago.  I contacted the webmasters at each site with the outdated external link notifying them of the updated URL.   I want to check how many have been updated, so I reran the report.  Unfortunately, there are some that I know were updated still showing up on the report with the outdated URL.  Any suggestions to get a gauge on how many have been updated?

From the Linkscape FAQ :

3. How often do you update your index?

The internet is really big and grows really fast! Crawling all of the internet’s webpages takes a lot of time and money. Our goal is to update our index every month. As time goes on we are confident that this time will decrease.
