If you stick with SMS messages, the weakest link will always be the carriers
SMS gateway. Since this is the last item in the chain, any upstream service
will still be handicapped by the gateway. I've worked with a variety of
carriers, and they have all had problems at one point or another with their
SMS gateways getting overwhelmed with SMS spam, etc.. causing long SMS
delivery queues or dropped messages. If you can find the SMS gateway admin
at Verizon they can probably comment on what the issue is and any planned
resolutions, else you may need to switch providers to one with a more
cluefull SMS gateway team.
So far this year, I have only had a couple instances of delayed/dropped SMS
delivery via the AT&T/Cingular SMS Gateway..

We've noticed that 1234567890 at vtext.com is no longer a very reliable
form of delivery for alerts from Nagios, et al. It seems as our volume
of alerts has risen, our delivery rate has dropped precipitously.
We don't expect much trying to actually reach a postmaster for vtext.com
so I thought the better question would be to ask what the current
best practice is to get SMS alerts out?
Back in the day, I remember a company I worked for had something called
a TAP gateway. Is that still a good route? I've also been told to
check out an SMS gateway/api service called clickatell.com -- anyone
using them to delivering timely notifications?
Is the best thing to do to try and get a programmable cellphone in a
datacenter?
What else are operators doing to get the pages out when things go wonky?
