Possible Facebook RADB source issue?

[alan-gibson]

We have been seeing errors for Facebook crawlers in the last couple of days. Walking through the code it seems to fail when source is not provided to the Irrc client:

client.query :radb, 'AS32934'
result = client.perform
Connecting to whois.radb.net
Processing AS32934
Executing "!s-*"
Got "F One or more selected sources are unavailable.
"
'!s-*' failed on 'whois.radb.net' (F One or more selected sources are unavailable.). when processing AS32934 for AS32934
No more queries
Closing a connection to whois.radb.net
Queue 0 guard objects
=> {}

Once a source is provided it seems to behave more as expected:

client.query :radb, 'AS32934', source: :radb
result = client.perform
Connecting to whois.radb.net
Processing AS32934
Executing "!sradb"
Got "C
"
Queue new 0 queries
No more queries
Closing a connection to whois.radb.net
Queue 0 guard objects
=> {"AS32934"=>
  {:ipv4=>
    {"AS32934"=>
      ["31.13.24.0/21",
       "31.13.64.0/18",
       "31.13.64.0/19",

Could something have changed with the service?

I am also seeing the same. Any help would be appreciated.
