Russian GLONASS Down For 12 Hours 148
An anonymous reader writes "In an unprecedented total disruption of a fully operational GNSS constellation, all satellites in the Russian GLONASS broadcast corrupt information for 11 hours, from just past midnight until noon Russian time (UTC+4), on April 2 (or 5 p.m. on April 1 to 4 a.m. April 2, U.S. Eastern time). This rendered the system completely unusable to all worldwide GLONASS receivers."

The system shutting down while still broadcasting "gibberish" seems awfully inconvenient. Sure they just didn't switch to encrypted transmissions?

Newer phones have location chipsets that support both GPS and GLONASS. Do they figure out automatically that the GLONASS information is bad and switch to using GPS exclusively?
To promote their system, Russia decided to make new smartphones without GLONASS support illegal [gpsworld.com] in their country -- so major manufacturers added that capability to all their phones (since there is almost no additional cost to each unit, once the capability is designed into the chipset). Not sure about CDMA chipset, since there is no major CDMA networking in Russia.
Would be nice if we got Galileo GNSS and Beidou support too, but I'm not expecting it to happen unless they pull a similar stunt with their markets (well, China might).

If by "very recently" you mean 14 years ago (literally in the 20th century) that selective availability was turned off.....
As for your other points:
1. The U.S. did not degrade any civilian GPS when they invaded Iraq.
2. If you honestly think the Ukranians are beholden to GLONASS... which doesn't even work for the Russians a large portion of the time.. and are somehow too stupid to buy commercial GPS products that are made in Taiwan and used by the rest of the world, then I have a bridge to sell you.
Hell, even the Russians use GPS (quietly) even though they tout GLONASS because nationalism.

It was. The chain of event that follow the assassination were a pretty rapid and unlikely chain of events to have happened without that assassination.
If you are curious, reading the account of what was happening the day the Archduke Franz Ferdinand was assassinated is a comedy of errors.
It's also highly unlikely the WWII would have happened without WWI, since there would not have been the poverty and economic status Hitler used to gain power.
