This page serves to provide WLCG service criticality input from your experiment, updated after discussions and agreements summarized here. Please fill out theurgency and impact columns for services that are relevant to
your experiment and add services that are missing. The criticality column
holds the product of the provided values and is calculated automatically.
Please do not add very generic services like e-mail, web or SSO again,
as we know they are critical essentially for everybody and we do not want to
dilute the tables with information that does not really help.
Please do not remove services that are irrelevant to your experiment,
because the tables provided here will be merged with those of the other
experiments and such services may be relevant to them.
For reference, the "old" values are available
here.
