Jester - I used to use Safe Site, formerly Alert Site, but as my traffic and income and has continually fallen, I have had to drop these services. Every time I make a sale, my cell phone alerts me with a "kaching!" sound, so when more than a few hours go by without that sound, I know something is awry.
I did let my BBB accreditation lapse last Thursday (had since 2006), due to lack of sales, so maybe it had more clout than I thought. I'll bite the bullet and renew that tomorrow. I still suspect issues with HG's Provo DC.
