A screenshot showing that a connection to prod-ec-us-east-1.video.pscp.tv from my VPS returns a certificate issued by DigiCert to Twitter for that domain name valid for one year and the certificate chain is trusted.

   I'm getting a warning when I try to access https://prod-ec-us-east-1.video.pscp.tv about an untrusted certificate valid for 10 years issued by Allot to Allot, which seems to be an Israeli company that does DPI among other things.

   When I try to access the same domain name from one of my VPSs, I get a 1-year valid certificate issued by DigiCert to Twitter (which is the real owner of the domain name).

   From both places, the domain name resolves to the same IP address.

   Am I being MITMed by my ISP??
