A friend in Indonesia. We share what we know about networking, computers, anime and research.
My friend Kevin wanted to peer under Perfect. He has his own /48 of IPv6 and a /24 of IPv4, so I went to update the BGP router at CJ1.
MikroTik has a quirk: the filter has to be set first. I did not know that. The network went dark.
Emergency. Panic. Then I remembered a customer — one I managed using Perfect Network's dedicated L2 internet access to — who also has ten Unifi lines installed. I asked to borrow a remote PC on their side, logged in to Perfect's BGP router from there, and fixed the mistake in under thirty minutes.
What came to the rescue was not a command. It was thinking clearly enough to remember who had plenty of other internet lines.
No school or university teaches this. Understanding BGP, and the experience that comes with it, is the most expensive lesson there is.
