Solid blue line: routes announced. Dashed amber line: networks answering pings. Both as a share of T-Mobile's normal, from C111 IODA, lowest reading in each 2 hours; the shaded band is the incident. The network itself stayed at normal (lowest 99.1%): the problem was in message delivery, not the network.
