Good to hear from you. This is a deep network routing problem that the first contact tech support folks won't be able to deal with. I haven't had time to plunge into the long process of tech support yet and get things escalated to the level where they can debug these kinds of issues. Somewhere I have a direct number to the right folks in the wireless data group -- people who can mess with routers directly and do real debugging -- but I haven't had time to hunt for that number yet.
A couple of nights ago they were clearly doing some work on the data end, at least here in Denver, and all wireless data was down for hours around midnight. When they came back up the next morning, the fastmail IP's at NYI (where fastmail.fm is hosted) were no longer reachable.
I have several devices and have done a little debugging. This issue affects LTE and eHRPD, but not 1xEVDO. This would seem to indicate an internal VZW routing problem.
I don't know all the technical internals of the internetworking between LTE, eHRPD and 1xEVDO, but it could certainly be a configuration issue that went wrong when they were doing router or other network updates. These things happen. It's not a third party application issue, and given the isolation of the the issue to some (but not all) of VZW's wireless protocols, it at least seems probable that it's an internal VZW routing issue.
If it doesn't get resolved soon I'll have to take the time to get on the horn and see if I can get it escalated to the right support folks.
