Old track data disappearing?

For flights in the past few days, old track data seems to have disappeared in the history. Is this a bug you guys are aware of?

Can you provide specific flights?

Have noticed this as well for active flights as well. Was looking at DLH493 today - at first tracking was normal, but came back to look at it after about an hour and the flight path was gone as was the live track log which had been working as normal for the first hour or so. It now simply says “No History.”
Not sure if this is the same problem that Element94 is having though…

EDIT: And it’s all back up…
