In case you, like me, have a large number of email->paging forwards in place for group-paging and other operational and commercial purposes and were suddenly surprised today by chunks of 300/minute warn/undeliverable msgs for @mobile.att.net addresses: Apparently their MX (mta01.cdpd.airdata.com) had a little meltdown a little while ago: from 12:18pm to 1:05p EDT, the MX refused connections entirely. Whoops, and now that I write this, both NS's are off the air as well. Should I hardcode my own MX entry into a local zone to overcome this? I am getting tired of 300 mail warnings every 15 minutes. Ouch. Ouch. Ouch. [rant mode on] Millions without working paging on their AT&T phones. For a little while. Not that it ever works terribly predictable when it's actually up either, but it's gotten better lately. Instead of paging delivery times ranging from 10s to 6hrs, it's only been 10s to 30m for me in recent months. With SMTP transport times over 1000's of pages consistently under one minute. AT&T reps: "It's the Internet's fault" A single-homed MX, even if there's a load-balancer there, and 2 nameservers, all in what appears to be the same announced /24 from a legacy McCaw AS, makes you think how much "importance" some incompetent beancounter at ATT WS has assigned to this loss-leader of a profit-center within their wireless range of products. Translate: because we give it to (nearly all?) our customers for free, we don't have to care about how well it works (the same could be said about their crappy, overloaded CDPD network, which is seemingly back-hauling every last CDPD frame in the country to washington state (via FR?) before de-capsulating it and letting those IP frames lose. Ever wondered about those 600ms ping times and 5 kbps effective transfer rates and why "free unlimited Internet" wouldn't entice you or me to ever pay for such a "performance" ? (let alone them charging you at a rate that would make every 900-number operator blush about the $/min flow. if you hook up your PC via a 'tethered' connection as described in the phone's manual, you'll discover after the next billing cycle that they've raped you for $0.05/KB, (e.g. up to $5.70/minute) conveniently hidden in the VERY small fine print on their website, for making use of their "free unlimited Internet". that is false and misleading advertising at the least, and outright bait&switch fraud at the worst - but hey, "very few customers are using this functionality", "there is no support for this type of operation", "I know nothing about this", "It's just in the manual because we couldn't tell Mitsubishi to remove it before printing them." You get the idea. Add to that that I am on my 3rd Mitsubishi T250 phone now ( in 10 months, I have stopped requesting new phones a while ago), the first one had ridiculously strong far-side echo for all my callers, and the latter 2 hang almost everytime you switch it into CDPD mode, except if you do it rather soon after power-cycling it (read: taking the battery out, due to the hang). And that was the early-adopter top-of-the-line model the most money could buy with AT&T last summer, gee. Why does the wireless data market not take off the way we thought it would, uh oh? boy, do I have news for my bosses, Omnisky, Aether, and Palm: lets get the hell out of this business.
