With https://github.com/toralf/torutils/blob/f307866d2149bcd3c95df5269b3b48d051f871e9/info.py I monitor the status of my 2 Tor relays. A day before I commented out this section in torrc:
#FetchDirInfoEarly 1
#FetchDirInfoExtraEarly 1
#FetchUselessDescriptors 1
#UseMicrodescriptors 0
#DownloadExtraInfo 1Now it took 7 minutes to finish (when those config values were set it was much faster).
But more interesting I realized today I crash of one of both Tor relays:
