It is with sadness that I report on the closure of Jon Lewis's NJABL blocking list. From the NJABL website: "March 1, 2013: NJABL is in the process of being shut down. The DNSBL zones have been emptied. After "the Internet" has had some time to remove NJABL from server configs, the NS's will be pointed off into unallocated space (192.0.2.0/24 TEST-NET-1) to hopefully make the shutdown obvious to those who were slower to notice."
NJABL (Not Just Another Bogus List) had been in existence from at least January 2002. Congrats to Jon and team for a pretty good run of eleven years.
Update: I received this in email: "Today, April 29, 2013, NS for the NJABL DNSBL zones is being pointed into 192.0.2.0/24 (TEST-NET-1) which is unrouted IP space. This will likely cause any systems using the NJABL DNSBL zones to experience long delays in DNS resolution of NJABL DNSBL lookups. This is being done both to sink the DNS query traffic and to hopefully be noticed by the owners/managers of those systems."
