AT&T Email/SMS gateway outage

Mon Jul 25 12:00:25 UTC 2011

Marginally operational, but I'm sure there are at least a few folks using
that service as part of monitoring, so it probably bears mentioning.

AT&T appears to be having an email-to-SMS gateway issue.  Messages sent to
xxxyyyyyyy at txt.att.net are not being delivered to handsets.  No bounce, but
no delivery either. As a workaround, messages sent to
xxxyyyyyyy at mms.att.netdo do get delivered.  Confirmed in the NYC metro
area and in Chicago at the
moment.
