Pulsant continued to announce my prefixes after I pulled my routers and then withdrew them within ~30 mins of asking why.

  • Co-incidental ~48 hour BGP Hold Time?
  • Weird config mistake their side?
  • A spooktacular Supermicro IPA EI box MITMing my uplinks?

@steverjuk got dual 1Gb FTTP (CityFibre/OpenReach) with BGP and plenty of rack space at the house so a bunch of stuff is temporarily here.

Will be moving some misc stuff (secondary DNS, secondary MX etc etc) into Vultr once I take the time to crunch the numbers on VMs vs Bare Metal instances (annoyingly they don't support BGP full tables to Bare Metal servers but can send full tables to VMs?!?)

I've got quotes from LINX for a 1/4 cab in London (with peering but no transit), RedCentric in Reading (transit, no peering) but Cogent in Amsterdam or iFog in Zurich (with peering at CHIX-CH / NLIX) feel like better options but I need to see what hell BREXIT will cause with shipping a tonne of servers over :/

Currently trialing iFOG with a virtual peering link over to their FOGIXP and will be turning up the CHIX-CH peering later this week.

Final trip to Pulsant Reading SE-4 (as it is now known) today.

Weird to think that ~15 years ago I literally helped build it.

Ah well.
