SMS hinkiness on AT&T?

Is anyone else seeing issues with multiple copies and delayed originals for SMSes on the AT&T network? I've been seeing this behavior for about the past 24-36 hours. This is phone-to-phone, not email-gateway stuff. Includes both new iPhones and people on T-Mobile as well as $random_att_handset. Given that our (royal we here) network monitoring is gatewayed directly via a phone... this is of some annoyance, to get interface transition and other alarms hours after the fact. I'm an old AT&T Blue customer if that makes a difference. Anyone? Bueller? -r
