[tor-relays] bridge behavior question

[Arisbe]

Hello all,

I have run a number of Tor nodes for five years but I started adding a 
few bridges last year.  I have one bridge recently installed on a lease 
VPS that has not reported a single inbound connection in over 40 days 
(except for Bifroest hanging out).  I see up to 4 outbound connections 
and usually see between 4 and 14 circuits.

The IP tables are correct and torrc is copied from successful bridges 
except for IP address.  The Tor version is 0.2.9.14 and the OS is debian 
9.0 (stretch).  I'm running obfs4proxy.  I set ORPort 9001 and ORPort 
[IPv6]:9001.

Tor | Metrics reports Advertised Bandwidth = 8.0 KiB/s for this bridge.  
Tor | Metrics reports Advertised Bandwidth for another working bridge I 
have with the same hosting company at 598.7 KiB/s.  I suspect this 
variation is due to lack of connections by the unused bridge.  I loaded 
a speed checker and it reported 72-Mb/s.

Can anyone give me some steerage to help me get this bridge productive?
