Not naming the facility, sorry. Learned that lesson when I named a provider in 2019 and their "community manager" rang my mobile for three weeks.
I will say it's not Equinix. Their queue was worse. Sixteen weeks quoted for a 3kVA single feed when I checked last autumn.
Own ASN, yes. RIPE allocation, been holding it since 2014. RPKI is done, ROAs published, but you're right about the IX filters -- LINX Manchester took four business days last time I added a new origin. I submitted the LOA yesterday afternoon.
