Current version of Feed43 engine has been written in plain old Perl. As the number of feeds reached 7000+ and we have had several hits per second, our hoster couldn't help but disable the engine script. When we created Feed43 we didn't even imagine it would be so popular despite its "techie-ness" (regular expresions, you know).
We tried our best to make our paid users continue to use this service without interruptions. As a side effect of disabling free feeds they have good times now as their feeds are being processed almost instantly. :)
But we still want to have a free version of Feed43 (this is why we called it so). Now we are busy porting the engine under mod_perl. This is a tough task, but worth doing. Current estimates show that scripts run about ten times faster. This is a good news.
Once we have the engine ported, we will move to a special server that will host Feed43, and launch it for public access again.
Our estimates for completing migration are about 3..4 weeks, if everything goes well. So, take a deep breath and wish us luck. We know you will miss Feed43 during this period.
