Hosting support

I'm building a site for my company that will have 20,000+ users, most of which will log in at least once a week. They will mostly be blogging and commenting and uploading photos.

I need a hosting solution that can handle tens of thousands of users and photos. Money is not much of an issue. I'd rather have something that stays up all the time rather than something cheap.

After doing some research, it seems like a managed dedicated server would be my best option. Is this correct? Anyone have hosting companies they've been particularly satisfied with?

Thanks!

I purchased domain pharmagalaxy.org from Google Apps for Free. then i purchased Bluehost hosting. my domain redirects to Google sites even after installing Drupal. What should i do to correct this?

My production live site is on godaddy ultimate shared hosting on linux. I have the same code base on both these places. But the production site is throwing internal server error 500 from the past 3 days. I have the login destination and front page modules installed and this 500 error happens only when users login and being redirected to a different landing page.
I set up such that anonymous users go to http://www.mydomain.com/publics and when logged in on this page, they get redirected to http://www.mydomain.com/landing.

This setup works perfectly fine on the dev site, but in production, I am getting the 500 error when the redirect to landing happens. Once this error is thrown, if I just type any other url of the site, I am getting to those pages fine.

The only difference between the dev and production site is the data in the DB. Both the sites were working fine for many months now and this 500 error has been happening since last 3 days only. Obviously, the godaddy tech support is of no help. THey just said they did some apache update on all servers 3 days ago and have been adamant that it has nothing to do with my issue, but the timing of when my issue started is so close to this update.
They are suggesting I move the site to a different server to test. I am a bit nervous about this and don't want to lose any prod data.

Hey !
So this is my situation guys : I'm a french Drupal Developper who's looking for a dedicated web hosting solution to install many drupal sites. Every sites is independent by its code and the average site in quite small in content and visitors. However I'm going to host 10 french websites for beginning and I will host ten times this volume in a year or so. So I need something very scalable and of good quality.

I have my site set up so it redirects me.
when i typed in my site address it gave me this error
403 Forbidden

Hi,

Q from a Drupal Noob,

Something probably discussed in earlaier topics but I am struggling now for 2 day to get my site online. Installed WAMP server on my local machine, created a site, tested it ... All works well (C:\WAMP\WWW\[SITEDIR]) via the localhost\sitename URL ...

However : asked for hosting space at edpnet (Belgium) and tried to move everything to hosting space (confirmed as being drupal 7 compliant).
