Florida-based intercity rail service adopts Starlink
Brightline said it has become the first passenger rail company to offer Starlink satellite broadband, which it plans to deploy on a total 10 trains connecting cities across parts of Florida this summer.

Mozambique and Kenya are the only 2 countries on the map that are marked as going live this quarter.
Most countries that don't currently have service are either marked late 2023, marked as 2024 with no mention of what quarter, or just listed with no date (but blue meaning it will come eventually, or gray meaning that country is on the naughty list and won't get it in the foreseeable future).

AT&T tries to block Starlink/T-Mobile plan for satellite-to-phone service
AT&T and rural telcos say Starlink-fueled phone service would cause interference.

AT&T and other entities are trying to block the SpaceX/T-Mobile plan to provide Starlink satellite service directly to cell phones.
In a filing yesterday, AT&T urged the Federal Communications Commission to reject the SpaceX/T-Mobile proposal. "The FCC's rules do not permit SpaceX's proposed use of T-Mobile's terrestrial spectrum, and Applicants fail to even request—much less justify—rule waivers that would be necessary to authorize their proposed SCS [supplemental coverage from space] authorizations," AT&T said.
AT&T said it is interested in the proceeding because it has a license to use adjacent spectrum in the PCS C Block. AT&T says the SpaceX/T-Mobile plan, which was announced in August 2022, could "jeopardize or inhibit the delivery of terrestrial wireless services," including mobile broadband.
As was Thanos, so was this filing. Of the various hurdles direct to mobile service faces, the regulatory battleground was always going to be at the edge of terrestrial coverage.
Certainly a problem T-mobile needs to solve for themselves--as does any other MNO providing service through Starlink on their own frequencies--is self-interference, where halfway to the boonies the terrestrial and space signals are basically the same power levels and thus compete for The Love from the user's device. That manifests kind of like in the olden days when your radio would pick up stations from two cities broadcasting on the same frequency. Its plausible that some combination of geofencing and frequency segregation and protocol-level hooks can enable the system to know how to talk to the device...but importantly this is not a regulatory issue as it is all internal. (There still is the regulatory issue that, to date, MNOs aren't blanket approved to use their frequencies from space...though that's probably going to happen or at least more or less happen at some point)
The issue is when that interference harms a competitor; It is VERY easy to imagine a scenario where the terrestrial edge of coverage signal for MNO X is so weak that the rolloff from frquency-adjacent MNO Y's space signal burns hotter. Historically this kind of scenario has always been where regulatory beefs come into play. What it comes down to is: is it fair that MNO X customers are slighted at the expense of MNO Y? And there's a corollary to that, which is: what kind of precedent does this set? Of course this is not a new concept--these entities ostensibly already have adjacent terrestrial frequencies and have figured out coordination (officially or not), and it's likely those existing precedents are what the likes of T-mobile will leverage.
IMO, worst case this eventually gets solved with some kind of mutually agreeable guard band in the offender's spectrum (T-mobile, et al), which of course will reduce or at least notionally reduce the level of service available to the offender's customers.
An estimated one million previously offline people in Mexico are now on Starlink via community service.

Good news: Got the email that my 2021 Residential order is now ready
Bad news: No way to indicate I already have a Dishy (Roam) and don't need another kit ($599).
Good news: My address shows up as available now.
So...
Place new Residential order
Specify I have hardware
Cross fingers
On existing account: cancel, transfer
Enter Dishy ID on new order
Order
Exhale as it all worked

The midwest US no longer has a clearly defined diagonal line, the next most obvious line to go is this jagged horizontal line in Illinois/Indiana/Ohio/Pennsylvania/New York.
Shouldn't be too terribly long (weeks?) until this line is broken up also.
essentially this blob will shrink on the north quicker than elsewhere and will be swiss cheese as population density is

Looks to be about 40°, though it's hard to imagine there's much significance in that number (given that its such a long east-west nuevo Mason Dixon) beyond "we need to cut this off somewhere for now and that looks about right".
The darker blues farther south are a function of population density and terrestrial service density (so, demand) vs constellation density (supply). Plenty of sats farther north to provide capacity, plenty of people down south that need capacity.
I wonder how the data link did during the abnormal attitudes.
