Internap so far in 2015:
| ||Jan ||Feb ||Mar ||Apr ||May ||Jun|
Internap does hosting, colocation, and cloud services, and like
another such services, New Jersey International Internet Exchange LLC (NJIIX),
appears to be having a bit of a problem with spammer infestations.
NAICS 518210 is Data Processing, Hosting, and Related Services.
While Internap ranks #44 in composite Borda, that’s apparently
because a relatively small number of nodes on one ASN at Internap are sending
a lot of spam, since Internap actually ranks #2 using CBL volume data
for both NAICS and U.S.

Belgium NV‘s AS47377 KPNBE got cutwail

its worst cutwail urge in the middle of the month.

Ideal Hosting was most improved in Turkey in
Classic.SpamRankings.net from PSBL data.
CBL data, DorukNet was most improved, dropping 41 ranks from #3 to #44,
and from more than 11 million to less than 33 thousand
spam messages seen.
Four other ASNs dropped out of the CBL top 10:
Netdirekt, DGN, NetInternet Bilgisayar,
Two of those, DGN and Sadecehosting, also Continue reading Ideal Hosting most improved in Turkey April
ROSTELECOM-AS came from nowhere to #1 on
the PSBL April 2015 RoW rankings, and seven other
Russian ASNs that weren’t even in the top 250 in March made the
top 10 in April. Perennial winner AS4134
CHINANET-BACKBONE got pushed down to #1, spewing less
than half the spam of AS12389 alone, and nowhere near
the 80% of RoW top 10 spam from the eight Russian ASNs.
April RoW ranking does not have any Russian ASNs in its top 10, so
whatever the cause, this time PSBL was more sensitive in detecting it.
number 16 for April 2015 among U.S. organizations ranked
by Composite Borda count.
On one of the four rankings that go into that composite,
Sprint ranked #1.

it balances several different sources so pertubations
on any one source (even if perhaps from Continue reading Sprint #16 in U.S. Cloud.rankings.net
Why so much spam lately?
Partly new(ish) techniques.
After noting that the
Cisco 2015 Annual Security Report
says spam volume went up 250 percent between January and November 2014,
CP Morey wrote for CIO.com 27 April 2015,
Spam continues to thrive thanks to ‘snowshoe’ strategy,
Detecting and blocking massive floods of spam from a single source
is simple. Most organizations have some technology in place capable
of identifying a high volume of email originating from a single IP
address and rejecting those messages as spam. Spammers know this as
well, which is why they’ve come up with a new strategy to circumvent
that detection: the “snowshoe” strategy.
A snowshoe enables Continue reading Spam Snowshoeing across Experts
Sending more spam from more hosts placed Internap #63 in the
March 2015 Cloud.SpamRankings.net,
compared to #85 in February (#1 is worst).
This is for all ranked organizations in the U.S.
To see this,
select the month, and then under Choose Rankings Classification
Internap’s composite Borda score was held down by slightly less
spam seen from slightly less hosts by one blocklist (PSBL),
but the increase in both spam and hosts by the other (CBL)
pushed it closer to #1.
However, InterNAP did greatly reduce its spam volume during the month,
as seen in the volume graph here, which you can get by selecting
Source: CBL Volume.
