Shaw null routed a specific IP

Yesterday I got this when tracerouting 140.211.10.6

1 OpenWrt.lan (192.168.0.1) 3.853 ms 3.833 ms 3.824 ms

And that's it. I was unable to ping or reach in any way 140.211.10.6. Meanwhile other servers on the same class C like 140.211.10.5 (which is the same server btw) and 140.211.10.16 worked fine:

If this is not a botched up DoS protection attempt from Shaw then I do not know what it is. Lasted for about half an hour.

I have asked Shaw for an explanation via chat, got none, shot an email, if that doesn't give me an answer then it's good bye.

It gets better. Shaw routes git sites differently? WTF! Look at this:

traceroute to git.osuosl.org (140.211.166.114), 3 hops max, 60 byte packets

That's pretty harsh. That's like asking the Receptionist at a car dealership details about why there's clicking coming from the engine on the highway. Receptionist doesn't have a direct answer, and to be honest, trying to track down a network engineer to look into something like that isn't exactly something that will happen lickety split.

Tracert seems fine for me within the Shaw network. Probably a temporary routing issue that was resolved, quit freaking out over a single IP, or routing going 2 different paths, jeez.

Your basing that off a single incident that lasted 30 mins and your only proof is 1 IP in a block failed a traceroute, hum maybe a router or link went belly up for a bit and as per you 2ns post they have load balancing. so one router could have handled some IPs and the borked one had that IP.

Wow 30 min interruption to a single IP on a residential (guessing) account with no SLA.... You should probably leave and go get a line with an SLA that say every IP will be accessible 99.999% of the time or else, good luck with that.

...Seriously?
To put some technical perspective into this :

a) so what exactly did you need from 140.211.10.6 that you noticed this?

b) checking the ARIN location of 140.211.0.0/16, looks like it belongs to the Oregon State System of Higher Education

c)

Do you have any background in Networking? Specifically, what dynamic routing is, and how it works?
Keyword, DYNAMIC.

Also, given the number of ways to proxy / loadbalance / NAT / redirect / etc. these days, an IP
address is rarely just an IP address these days.

There's probably more at play than a simple "null route gone wrong" here, but reducing yourself to
the emotional level of an infant isn't going to help your case or help you get the answer(s) you're
looking for.
