Missing days in "Bridge users by transport"

Do you know what is the cause of the missing data between April 14 and April 22 in this graph? I'd like to be able to account for it when I present the graph. https://metrics.torproject.org/users.html?graph=userstats-bridge-transport&t... I don't suppose it is a problem with the bridge, because other transports show the same gap. https://metrics.torproject.org/users.html?graph=userstats-bridge-transport&t... https://metrics.torproject.org/users.html?graph=userstats-bridge-transport&t...

Hi David, April 14 to April 22 was the time when Tonga, the bridge authority, was offline due to Heartbleed. As a result, we didn't archive that bridge's descriptors nor Tonga's network statuses, both of which we need to estimate user numbers. All the best, Karsten
