I didn't want to clutter up the corporate GibsonResearch Twitter account with lots of personal stuff. That's what this one is for.

    By popular demand... I am (briefly) pausing work on SpinRite v6.1 to create a new piece of GRC Freeware which will quickly and non-destructively check the terrain of any USB-connected mass storage drive for “fakery” - It will quickly spot “fake” or badly damaged drives.

    Facebook may have "deplatformed" itself, along with Instagram and WhatsApp. Hope no one depends upon "Login with Facebook!" Whoopsie! Somehow, the BGP entries for Facebook's DNS resolvers have been withdrawn from the Internet's routing tables. Insider? Attack? Who knows. Wow.

    The world's DNS servers are seeing 30 TIMES more traffic since DNS caches have drained for Facebook, Instagram and WhatsApp. Users are inadvertently pounding on them. (Cloudflare's 1 . 1 . 1 . 1 DNS server(s) are holding and remain speedy.)
