said by Anon547e0 :Is comcast aware of this issue?
"Comcast" is too large of a company for everyone to know any particular detail. However, it appears that a few of the lead engineers (that just happen to occasionally be around here) understand it, and (I am guessing) will be passing that info along to the appropriate people during the day (and presumably roll out mitigations for the time being until they can get the updates worked out).
I would never expect such information to reach down to the average CSRs you get on the phone, and unfortunately the word "Shibboleet" was just a dream.
