Hi lovely network team. Iain is working on a script to inform him of hidden service descriptor age. He's using stem to fetch them but unfortunately after a few HSFETCH calls it begins to fail with QUERY_NO_HSDIR. Maybe some attempt at rate limiting? Once the tor process gets into a borked state it doesn't seem to recover until I bounce the tor process. Here's an example of my first query (which succeeds)... ``` >>> SETEVENTS HS_DESC HS_DESC_CONTENT 250 OK >>> HSFETCH facebookcorewwwi 250 OK >>> /events HS_DESC_CONTENT facebookcorewwwi 3jjxhgi72xguhnihk4nwzrcpyvwf3ml5 $DA722ECCB9C0DE462C4FA585B93C99CCCA1C7547~SIRDRAKE2018 rendezvous-service-descriptor 3jjxhgi72xguhnihk4nwzrcpyvwf3ml5 version 2 permanent-key -----BEGIN RSA PUBLIC KEY----- MIGJAoGBALfng/krEfrBcvblDiM3PAkowkiAKxLoTsXt3nPEzyTP6Cw+Gdr0ODje hmxTngN1pKiH7szk4Q1p2RabOrUHWwXmGXeDDNs00fcyU6HupgqsCoKOqCsmPac6 /58apC64A7xHeS02wtfWJp6qiZ8i6GGu6xWXRWux+ShPgcHvkajRAgMahU8= -----END RSA PUBLIC KEY----- secret-id-part wuyfue4erz2hlh4d5o4kduweosco6rw4 publication-time 2018-10-31 18:00:00 protocol-versions 2,3 introduction-points -----BEGIN MESSAGE----- aW50cm9kdWN0aW9uLXBvaW50IHR6c3U3ZXh5amVlZWU2cm92cDd1Z25lM3pxemlo ZHk1CmlwLWFkZHJlc3MgMTQ0Ljc2Ljk2LjYKb25pb24tcG9ydCA5MDAxCm9uaW9u ... lot more base64...

If anything's needed from me on the stem front just let me know.
