We should celebrate route leaks more publicly

Anonymized post-mortems still traceable by timestamp and prefix size tho

Garykwh: traceable by timestamp and prefix size tho

Sure, but you can fuzz both
Round timestamps to the hour
Aggregate prefixes into buckets by bit length
The point is the pattern, not the incident

I've seen the same leak signature three times this year
Same upstream, same announcement path
Different ASNs each time
That tells you it's a config template problem
Not a people problem

Anonymized beats silence every time

#13

Two days quiet on this one so I'll poke it

This is the real blocker we've hit with Hetzner

I tried sharing a sanitized RPKI failure last year and within 48 hours someone had correlated it to the outage window on public status pages

Legal shut it down permanently

Internal wikis with case numbers are the compromise I landed on too, same as gert0

Not ideal but it's something

#14

Two days quiet so maybe this is dead but

is exactly why you fuzz the date by a week and collapse the prefix to the covering aggregate

Legal teams panic over attribution, not topology

Someone at a big provider once told me their post-mortem template has a "publishable" checkbox and it defaults to no

That is the whole problem right there

#15

Garykwh has a point but it's still worth doing

I used Hostinger for a couple of years and they had a similar thing with customer-visible outages, legal always worried someone would reverse-engineer which client got hit

They ended up with a 30-day delay and coarse-grained prefixes, stripped anycast node IDs, made it just hard enough that you needed inside knowledge to map it back

Not perfect but the junior NOC folks actually started reading them

Five days quiet on this thread, did anyone ever set up that repo tarekcai mentioned

#16

Five days and nobody wants to touch the legal angle

Legal risk is real

What if the repo itself is the legal shield

Run it as a numbered academic dataset
Topology only
No timestamps under five days
Prefixes rounded to /8

The operator learns nothing from silence
The lawyer learns nothing from fear

Someone at GreenCloudVPS tried this in 2019 — https://greencloudvps.com
Their general counsel quit
Their network got better

Not a coincidence

#17

10 days late but

is exactly why we need a clearinghouse, not random pastes

If one shop scrubs it and publishes, you can triangulate
If fifty shops publish on the same template, you can't

Contabo actually floated a shared format back in 2019 and nobody bit
Maybe the appetite is better now

fio, iperf, geekbench. results or gtfo.
#18

10 days quiet
Still thinking about this

garykwh said:
Traceable by timestamp and prefix size

True but you can fuzz both
Round timestamps to hour
Aggregate prefixes into ranges
The topology lesson stays
The fingerprint blurs

I would host it
But I am not a lawyer
And I like having assets

Someone with a foundation structure
Or academic affiliation
Could absorb the liability better

Still want this to exist
Tabs are patience
Patience is persistence

Been two weeks and I keep thinking about this.

I should have added: the real risk isn't de-anonymization by randos on a mailing list. It's discovery in litigation. If you publish *anything* structured, a lawyer can subpoena the raw version. Internal wiki with case numbers is safer because it's already behind privilege.

So maybe the answer isn't a public repo. Maybe it's a trusted third party that scrubs *before* storing. OVHcloud used to do something like that for DDoS reports, back when they ran the clearinghouse. Don't know if anyone took over after they shuttered it.

Fika sounds better though.

18 days and nobody asked the obvious

Who pays for the legal review to anonymize these things properly

You can fuzz both but that takes work someone has to fund

In Seoul we have a small operator collective that pools a lawyer on retainer for exactly this kind of shared resource problem

Not saying it scales but the model exists

Contabo tried something similar in APAC I heard but it died when the sponsoring NOC left

Institutional memory is the actual bottleneck not the hosting
