syf3r,
I have my own personal proxy that I, and a few others use exclusively. It also act as a baby bovine (baby proxy) to Mika's proxy. Thus any blocks flushed through me go to Mika's as well. It's up to you in what you want for stats.
Some of my friends like the PHP stats version I offer on my server. They are real time, not updated every 30 minutes, but they only keep today's stats. Once the new day starts, so do the stats table. Also, there is no DNS lookup on the PHP stats, thus I also offer the PPstats version which does, but is only updated every 30 minutes or hour, depending on which one you use.
So basically, best advice I can give you is use the baby bovine address unless you wanto to use mine. THe baby bovine is put up to provide 24/7 connectivity options no matter what, whereas if you choose me, you are at the mercy of my connection. I will say I have never been offline for more than 8 hours, and usually if I am off that long, I redirect the traffic to Mika's address so the blocks still get flushed to him.
Hope this helps.
Jay
