Dynamic site dropped from Google, PR the same

Lost backlinks, index and cache !?

[Howardtd]

Hi all

I'm new to this forum (been reading it for some time) and i have a simple question.

Recently (within the last 6 months) we changed the way we linked internally in our dynamic websites.

We went from link/pages like this :
page.asp?pageid=44
to
page.asp?pageid=4BF87A72F3A24A79A5AA6FAAAEFABB0B

Since this update was made, all our pages has gone from the google index (our PR is the same - 5) could this be caused by the long id, or is it a change in google that just don't index dynamic contents anymore?

The fun thing is, that the site still understands the old id=44 link, and some of these old pages are still indexed in G, and the spider keeps visiting them, but from the frontpage of the site, google don't crawl any of the new links with the long id!

Thx
Howard

Actually our pages uses this syntax :

page.asp?page_id=44

page.asp?page_id=4BF87A72F3A24A79A5AA6FAAAEFABB0B

Can it be the "_"?

That is definitely something that may take time to show up. I still haven't seen some updates on some of my changed url's for months even with the updates.
I would say that your best bet is to be sure those old url's still forward to a decent section of your site so a user can still get around if visited.

Possibly a - instead of a _ may help? I am not extremely familiar with dynamic url's so I would be sure to wait for the reply of someone who does. This is just a possible idea yet I don't think the _ should make a difference.
