As bloggers who must duck and cover whenever the site explodes from massive traffic, BBCool has a fine appreciation for accurate traffic monitoring software. iWebTrack has announced an update to their service, featuring SMS or IM alerts when your site hits peak traffic levels, as well better handling of high-traffic sites. Also, they have what’s called iWebTrack LITE which is a mobile interface for BlackBerrys and other handhelds available to subscribers. For the whole shebang you’ll be looking at around $40/month, or $20 for standalone tracking. They’ve also got a month-long trial, if you’re looking for a test run.
