[RPKI-Discuss] Cloud Innovation Displays Very Poor, If Not Criminal, Netizenship

Hi all.

I'm not one to b**ch & moan in public, but per subject, I could not let
this one slide.

And if you get this from multiple mailing lists, apologies for that -
I'm just trying to make sure that this reaches as wide an audience as
possible, on the continent.

SEACOM (AS37100) acquired MacroLan (AS37353) a couple of years ago.
MacroLan is now part of the SEACOM family, and while we are in the
process of integrating that network into AS37100, some existing services
continue to be delivered on AS37353 until that exercise is completed.

One of the customers that AS37353 was providing services to was Cloud
Innovation, in Cape Town. From a routing perspective, because Cloud
Innovation had no AS number for this service, all of their IP address
space was being originated by AS37353, on their behalf.

In December of 2019, AS37353 ceased providing services to Cloud
Innovation. That is 6 months ago.

In recent days, it came to SEACOM's attention that some of Cloud
Innovation's IP address space was being originated by AS37353 -
specifically, - even though we were sure that they were
no longer a customer of AS37353 since December of 2019. At first, we
thought this was a cached entry in a number of popular looking glasses,
but then every looking glass had the same entry, which made this an
unlikely bug.

As of yesterday afternoon, see below what Telia's looking glass was
saying about this prefix:


Path #1: Received by speaker 0
  4809 134190 37353 (metric 2134) from (
      Origin incomplete, localpref 200, valid, internal, best,

    (RPKI state Unknown)

But when I run a traceroute from my house to that prefix, it clearly was
not ending up in Cape Town, where AS37353's main operation resides:

So we, then, realized that this was a fraudulent use of MacroLan's
AS37353, to which we had given no express permission.

As luck would have it, due to my days living and working in Malaysia, I
know the good folk that operate AS134190 (IPDC Solutions), who was the
upstream providing transit for this prefix. So I rang them up yesterday
afternoon, told them what was happening, and within the hour, they got
that eBGP session shutdown. I am most grateful to them for their quick
response and immediate understanding of what was going on. Even with all
the technology we have today, it, many times, comes down to having good
friends in good places.

Anyway, it turns out the ISP that had acquired this prefix from Cloud
Innovation is based in Manila, Philippines. When IPDC delivered their
transit service to them in Manila, that ISP informed them that they
should use AS37353 for the eBGP session. Yes, one could argue that IPDC
should have done their checks to ensure that the AS number being
provided by their customer belongs to them, but to be honest, I'm not
too bothered about that compared to Cloud Innovation's thinking that it
was okay to use another network's AS number in order to deliver their
services to their customers.

IPDC confirm that this service was activated for the Manila ISP in
December of 2019, right around the time Cloud Innovation's service with
SEACOM, in Cape Town, ended.

As it currently stands, the ISP in Manila is now off the Internet, with
some 12 paying customers currently without service. Their excuse - they
do not have an AS number of their own.

IPDC tried to find out why the ISP in Manila thought that it was okay to
use another network's AS number for their service, and as it turns out,
the network engineer at the Manila ISP that set this up has since left
the company. All the ones currently there do not have any history about
all of this.

Currently, is not in the global BGP table:


lg-01-ams.nl>sh ip bgp
% Network not in table

lg-01-nbo.ke>sh ip bgp
% Network not in table

lg-01-cpt.za>sh ip bgp
% Network not in table


That Cloud Innovation thought it was okay for them to use MacroLan's AS
number to originate their own prefixes into the global BGP is as morally
reprehensible as it is technologically distasteful.

SEACOM have been working very closely with AFRINIC to delete previous
route objects from their IRR that certify a relationship between Cloud
Innovation's parent /16 aggregates that cover this prefix, and AS37353,
but this is one of those objects that cannot be removed via the
MyAFRINIC portal, and requires manual intervention from AFRINIC.

I have not, personally, spoken to the proprietors of Cloud Innovation
and/or Outside Heaven, as I don't see how anything could explain this
with any degree of justification.

For now, I will find some beer to wipe the foul taste from my mouth,
while we (SEACOM) consider what to do about this.

And yes, for those who are wondering, RPKI's ROV would not have
prevented this, in its current form. This is AS hijacking, and ROV,
today, tries to solve the prefix-hijacking problem, first.

Thank you for your attention.
