Later edit: all of the below is, so far, incorrect again. Apparently they completed another round of tests.
Starting midnight today, 2+ hours ago. The connection gets established, but then it interrupts, reestablishes, and so on, in an endless loop. Here, an excerpt from the log. All gates are affected, including premium ones, except somehow Zurich. The resulting quality is abysmal: no pages open at all, and Chrome constantly reacts with a 'network change' error.
Coincides with other network problems which spiked in my region at the same time, so likely another round of DPI censorship. For example they also hurt legit Telegram traffic which works poorly even without VPN.
