The spamcop.net domain expired on Jan, 31 2021 today and for a few hours it was parked at Sedo Domain Parking.
Parking DNS resolvers at Sedo answered all wildcard of *.bl.spamcop.net with IP 91.195.240.87. Misconfigured email services not verifying the meaning of bl.spamcop.net's answer codes to be 127.0.0.1/8 and blocking emails regardless, were amplifying the bad consequences of this outage.
Unfortunately, as of now, neither the spamcop.net team or someone from the Cisco communication staff has issued a public statement or apology for the disruption of such world-wide significant service outage, likely caused by negligence or hard to excuse mindless cut cost.
Dear Cisco, Spamcop is a significant service since 1999 even collecting paid subscription for volunteer submissions. I am ok with that if it is properly maintained and work as intended, but here it clearly failed in a very bad way.
