+# Ride Closed 🚧
+
+Dear users,
+
+The Milk Sad vulnerability Lookup Service was offered for 90 days by the Milk Sad team upon disclosure as a free service to help users determine if their wallets were impacted by the Milk Sad vulnerability.
+
+This service has been taken down permanently and with prejudice.
+
+Understandably, we cannot keep the service running forever. While there were significant cost considerations in running this service in the first place, we felt it was the right thing to do.
+
+[The code for the lookup service](https://git.distrust.co/milksad/lookup) will remain open and available to all for as long as we can reasonably do that.
+
+Best regards,
+
+Milk Sad team

 To help people identify if they are impacted by Milksad, we are providing a web service to check if your mnemonic is in the vulnerable set. Note that this service -only- covers mnemonics impacted by Libbitcoin Explorer (`bx`) versions `3.0.0` to `3.6.0`, though it may be updated over time to cover other related vulnerabilities we are researching.
