https://cti-taxii.mitre.org seems to be down

[jpferrero]

Trying to connect to https://cti-taxii.mitre.org/ is failing with a 'connection refused'.

Still running into this issue.

This seems to be resolved for us now. As of EOD Friday the connection seemed to be intermittent, with requests only failing a fraction of the time. Our last failure to pull Indicators was Mar 22nd 2024 13:32:18 EST.

Sorry for the downtime - the TAXII server should be back up and running now. Thanks for your patience!

We are actively moving away from the legacy TAXII 2.0 server that has had many issues over the years (and will be taken offline on Dec 18th 2024 as we just announced in the ATT&CK v15 blog post) and are recommending that people check out the TAXII 2.1 server instead going forward. Hope that helps!
