To put a little more info (and to second XebEka Moonlight's issue).
Achlya, Sabra, Itame and Notata (and probably some neighbour sims) used to be a long way from a telehub (1180ish metres for my property in Achlya last I looked).
With all those new sims going in up north, some new telehubs got put in; notably in Siona and Ribeata. Now the Ribeata telehub is far closer than any of the others, but it's about a 3km trip to fly around the empty sims between it and us. Certainly we're no longer getting customers at our respective vendors (I'd wondered what happened to them all).
Much as I like the quiet...Maybe a TH in Notata might fix the problem? Or if LL is planning on plugging that gap anyway (and from the look of the terrain it seems that is on the cards sometime soon) perhaps stepping up the priority of those a little to return traffic to normal.
I'm starting to wonder if that's why so many of the nearby landowners have cleared out since the new Ribeata telehub went in.

EDIT: I notice the gap being progressively filled this-afternoon. It'll be nice to have some visitors again, and through traffic again. Maybe I'll get some neighbours back while the land prices are still artificially low here.
