Do NOT turn your appliance off.
Cisco is warning customers about an expired certificate bug in several of its Viptela SD-WAN devices, which can take down the boxes and consequently their attached SD-WAN environments. The issue affects the vEdge 100, 1000, and 2000 routers, which typically sit at the edge of the network and provide SD-WAN, security, and multi-cloud connectivity to enterprises. Cisco is developing a solution to replace the expired certificate and is working to support customers already impacted by the problem.
Twitter Lets Tor Onion Site Certificate Expire, Killing Off Privacy-Protecting Service
A bitter pill to swallow
Twitter has allowed the certificate for its Tor onion site to expire, effectively shutting down a privacy- and speech-protecting service that it introduced just last year. The certification expired on March 6th, just shy of two years since the site's launch. The Tor Project has reached out to Twitter to try to bring the onion version of the social media platform back online, but the future of the service looks bleak as Twitter has faced significant staffing cuts and struggles with the stability of its main site.
