    Nobody will ever need more than 512K for routing....

    TLDR: Public IPv4 address space exceeded 500k routes. Older routers (or routers that haven't had their config updated from the default allocation) have a max of 512K* available for IPv4, causing errant behaviour or ignoring new routes. Hilarity ensues.

    *[1] - "Theoretically the table should hold up to 512k entries, but the memory is not exclusively used for it, some of it goes to IPv6, some to maintaining various sessions, MPLS etc, so it dropped out at around 500k." -- From Nux!: 512k routes ought to be enough for everyone

    Meraki admin panels were apparently affected yesterday and mail delivery may be hit-and-miss.

    This does explain a lot of the junk that has been going down today, Vodafone in NZ or at least a stack of their edge providers probably use this as many sites were simply unavalible from mobile data.

    Seems about right. Some nice planning by the people who keep our internet running.

    I wonder if EE's lack of data is related... Or if its just yet another of their random bits of downtime.
