Hi, I want to also point out here that the «50% after one year» requirement as well as the «special circumstances» exception were not novel concepts first introduced by 2013-03, they were simply moved (and slightly simplified) from the general section of the policy into the IXP-specific section, as the need evaluation was being removed from the former. To be clear, it was our (the 2013-03 authors) intention to leave these mechanisms essentially as-is for IXP assignments specifically. The old pre-2013-03 policy (which covered both IXP and non-IXP assignments) read as as follows: «6.3 Utilisation Rates Assignments' immediate utilisation should be at least 25% of the assigned space. After one year, this should be at least 50% of the space unless special circumstances are defined.» See https://www.ripe.net/publications/docs/ripe-599 I have not attempted to figure out exactly when this language was introduced, but I suspect it has been around for a long time.
