 > 5/15/19, 15:55:40.969 [NOTICE] new bridge descriptor 'flakey' (fresh):
 $2B280B23E1107BB62ABFC40DDCC8824814F80A72~flakey at 0.0.3.0
 > 5/15/19, 15:55:50.471 [NOTICE] Guard
 $2B280B23E1107BB62ABFC40DDCC8824814F80A72
 ($2B280B23E1107BB62ABFC40DDCC8824814F80A72) is failing more circuits than
 usual. Most likely this means the Tor network is overloaded. Success
 counts are 144/287. Use counts are 62/68. 279 circuits completed, 0 were
 unusable, 134 collapsed, and 10 timed out. For reference, your timeout
 cutoff is 60 seconds.
 > 5/15/19, 15:55:50.475 [WARN] Guard
 $2B280B23E1107BB62ABFC40DDCC8824814F80A72
 ($2B280B23E1107BB62ABFC40DDCC8824814F80A72) is failing a very large amount
 of circuits. Most likely this means the Tor network is overloaded, but it
 could also mean an attack against you or potentially the guard itself.
 Success counts are 144/289. Use counts are 62/68. 279 circuits completed,
 0 were unusable, 134 collapsed, and 10 timed out. For reference, your
 timeout cutoff is 60 seconds.

 I'm glad you're able to connect :)

 There's no need to worry about this warning at the moment. We believe it
 occurs because of the frequent blocking or unreliability of snowflake
 proxies.
