I have no insight into what happened at TCL, but their 30 minute (as reported) outage seems mild compared to other recent large companies.


The latter was interesting; again, no insider info, but I did see a pronounced split in public rage, one side venting generically about Rogers customer service, "monopolies", the regulator, refunds, I WILL SUE YOU!11! and the other side disseminating the magic fix "change your DNS to and it all works again".
