Spotted a figure that is wrong or out of date, or a provider that belongs in one of the guides? This form reaches me, Sebastian Holt, directly.

What helps most:

  • the page it is on,
  • the figure or statement in question,
  • where the correct value is published, ideally a link to the provider’s documentation or price list.

Every correction is checked against that source before the page changes.

    Please prove you are human by selecting the plane.
