Hi NANOG community,
A few questions I have for the community regarding server lifts at colo
facilities.
1. Is a server lift something you would typically expect a colo facility to
provide?
if yes,
2. Do colo facilities typically allow customers to just use them or provide
an operator?
3. Is it
Hi everybody!
as part of laboratory work at the university, I'm working on a BGP
design study, and I would like to post some questions regarding IP
address space allocation and its impact on BGP which are breaking my mind :)
Let's suppose we have an ISP/AS with two POPs: PARIS and LONDON. T
I have noticed this and especially the strange format of the packets with a
SYN/ECE/CWR flag combination: http://pastebin.com/jFCDAmdr
This may be $whoever trying to establish network performance/congestion via
ECN or it could be something else like a fast scan technique or OS
fingerprinting

Maybe not super useful in your case but talking about SSH the sysadmin
solution would be to disable password login and use just keys.

I had this question posed by a marketing type in my office. Does anyone know
the answer?
Is it microsoft.com, msdn, outllook365, msn.com, outlook.com, azure, windows
updates, xbox? what else is possibly covered or omitted in their peering
service? I suppose we have a customer who is an Azure
When I talked to Frontier about our Office in Tampa, I was told there was a
fiber cut that was effecting SoCal and Florida. Not sure how the 2 were
related but that is what I was told. Our Tampa office has been down as well
since 7:00am local time.

I've been seeing abuse reports from Sony lately, indicating IPs are blacklisted
on the Playstation Network, mainly for attempted account compromise.

There are a lot of papers on traffic model, but it is still an open issue...

Yes, I would expect a lift at a colo but in terms of regulations (safety) I
do not think it is a mandatory requirement for most colo's
Allowing customers to use them can be a yes or no ; it requires some basic
operational skills to operate - you just cant trust a client visiting to
use it unless s

If you have redundant backhaul that completely fails, you've got real
problems.

As a practical matter, if they're using the answer for a security baselin
"your direct peering can be slow and congested, while
there's actually a longer but faster path through someplace else"
Possible, but unlikely for most networks.

My direct peering is within my control, the traffic has to follow basically the
same path internally to Internet and IXP. Internet path is definitely
variable. IXP path is definitely fixed. It's already there, just needed to
know what Microsoft provided (if anyone knew). Actually, a MS peeri
Hi Eric,
With this type of connectivity you have to pay attention to Traffic
Engineering...
And when I say, traffic engineering, I mean both ways.. how you are sending
traffic to them
along with how they are sending traffic to you... (sometimes a bit more
challenging to do).
I will give you t
Are respondents to suppose that the customer base and address space are evenly
divided between the two cities, and that the ISP is too clueless to originate
each /23 from the city that uses it, in iBGP?
