Yes, thanks to the Wayback Machine (at least for now)
Fortunately it doesn't seem that Wizard's robots.txt policies or anything else have precluded the SRD page and downloads from being archived by the Internet Archive project. I put in the page URL, randomly selected a snapshot from a few years ago et voila - all the files are available to download.
Unfortunately, if WotC does change their site robots.txt or otherwise forbids the archival of site content (or someone who owns wizards.com in the future does), the effect is retroactive and the snapshots of the archived page will go away. The archive.org collection of the 3.5e SRD pointed to by Carl's answer is probably a safer long-term resource.
I was pretty surprised to discover I didn't have this saved somewhere in my old documents folders, so I decided to also copy the archive and put all the files up on my personal webserver, for posterity's sake.
