Dear Relay Operators,

Please see below for an updated list of slow relay DirPorts.

It turns out that some of these relays are down, and the connections are timing out.
I've modified my script so it catches timeouts, rather than treating them as "success".

Here are the relays that are actually up, but timing out or producing slow DirPort directory downloads:
89.163.225.184:9030 - mertadx - No ContactInfo - 92139E58A2FD1235A9AC02B1E1E87174FB80301B

81.7.14.227:9030 - Torwell01 - cc'd - BCA197C43A44B7B9D14509637F96A45B13C233D0
62.210.238.33:9030 - ORGNorthEast1 - cc'd - FDF845FC159C0020E2BDDA120C30C5C5038F74B4
212.107.149.145:9030 - flimsy - No ContactInfo - A4B99A72464F955F7EFFB5DD968B53DD450C7FB4

(This is an incomplete list based on those relays with the highest bandwidth weights.)
