gs.debian.org/cgi-bin/bugreport.cgi?bug=3D952715=0A=0AWhen a request is ret=
ried because of a network interruption, on some servers I=0Awill repeatedly=
 encounter a 509 on retry. (I believe the 509 in this case=0Ashould be inte=
rpreted as a 429 to indicate too many concurrent requests.) If I=0Akill the=
 retrying wget and run it again, the request has no issues. I believe=0Athe=
 issue is because wget is reusing the connection from the initial failed=0A=
request to issue the request for the retry. =0A=0A2025-06-24 21:16:31 (24.5=
