Need to access Zimbra 5.0.8 Open source

[Sbhingarkar]

Hi,

Few days back we were using 5.0.8 version of open source.
But suddenly we found that the link to download the installable and source had been removed from the site.

Is there any way to get the access to the downloadbles?
Is there any specific reason of removing accessto it?

Please can any one guide us in this area.?

Thanks
