Mozilla hyped today's Firefox 3 launch with a 'Download Day' appeal to Firefox users to all come get the new version at once and shoot for a new Guinness World Record.
Mike Schroepfer of Mozilla wrote on the Mozilla developer center blog that you should head to http://getfirefox.com/ for the new browser (you can't yet get it by going to Help | Check for Updates within Firefox 2). That page appears to be coming up now, but for a good while the site was unresponsive.
Per Melissa Shapiro on a Mozilla blog posting from earlier today, "Our servers are currently feeling the burn and should be back to normal shortly."
I just talked to Kristen Whisenand, PR for Mozilla, who said their servers are churning out 14,000 downloads a minute.
So if you're trying to download and can't get through, or maybe get an "Http/1.1 Service Unavailable" error, keep at it. Whisenand says some individual requests may not get through because the systems are so busy, but that the servers are up.
