...and I wonder how your service map software copes, Grahame, when they are no delays or cancellations.....
Worries the heck out of me ... I keep thinking my data feed must be broken
I have been around sufficiently long to have various checks and balances in place; when our server plays up, I tend to have multiple flags letting me know, and except on rare occasions I carry tools to fix from just about anywhere. I have intentionally left the "Fastnet Rock" feature on the service map to give me an immediate shout if a station needs adding to my database of possible termini; the "zero option" is treated as a special case in the graphic generator as you'll note it uses the word "No" rather than "0" ... this sort of stuff is easy for me, but in the midst of a massive industry system such as we see on the various feeds, all too easy to overlook.
