  • Two 9s reliability?

    It seems that collectively** the UK banks have had more than 33 days of downtime within two years, I make that under "two 9s" rather than "five 9s"

    [**] yeah, sure it's not correct to just add up downtime across banks,
    but several of them have had downtime simultaneously ...
