issue when downloading from https://bridges.torproject.org/bridgestrap-collector
I have noticed an issue when collector-02 is downloading from: https://bridges.torproject.org/bridgestrap-collector
This is the error I see in java.

I made some little measurements from bash and got this:
```
time_namelookup: 0.050899s
time_connect: 0.097606s
time_appconnect: 0.159109s
time_pretransfer: 0.159138s
time_redirect: 0.000000s
time_starttransfer: 0.209088s
----------
time_total: 5.969495s
```
Seems nothing is really amiss. Any idea what is happening? Is this a web server issue or should I talk to anti-censorship instead?
