Look in your car...

If you have a recent vehicle (especially one with integrated nav,
multimedia radio and comms), it is likely that the system interconnect
is handled over Media Oriented System Transport (MOST) which is a
variation on traditional token-ring.

I guess this begs the question of whether or not we're seeing actual
layer1 going down or just the effects of mass BGP withdrawals.  Are we
seeing lights out on fibre links or just peering sessions going down?
Both could still point to a coordinated intentional blackout by the
Egyptian gov't though.

Obviously for the effected, the effects are the same. |8^)

However, I'm interested in knowing about the level of fine control that
the Egyptian government may have exercised.  I think the subtle
implications on the relationships between operators and governments bear
some fine distinction in such a case.

Also I think there will eventually be different consequences between an
indiscriminate mass disconnect of all telecom and network services and a
selective one where some of the infrastructure is left intact but under
tighter control... especially if internal reach is still selectively
available while external reach has been disabled.

Very good point.

For my laptops, nearline field storage includes my laptop's drive and a
portable external drive. Online and nearline home storage is a network
attached storage array running proprietary X-RAID (like RAID-5) with a
hot-spare drive. All my machines (desktops, servers and laptops) are set
to perform regular backups to the NAS. Offline backups are done to a
series of external USB HDs that are rotated into place for nightly
incremental and weekly full backups. Current retention schema is 4 weeks
of backups with a one week offsite physical rotation (performed monthly
to a safety deposit box).  I'm at the moment trying to figure out a good
way for doing streaming backups to an offsite DC.

I can understand that.  That's why I use a rotation and retention system
as well as two NASes syncing to one-another with the backups being
performed from the second NAS.  I treat them like I used to treat tape.
The onsites contain nightly incrementals as well as weekly full dumps.
These drives are rotated every week. Every month a copy of the latest
full dump is copied to another set of drives which are sent to offsite
storage.  I keep two copies offsite.  To implement this, I need a
minimum of nine USB drives.  I actually have 10 so I can have an extra
one onsite as a hardware replacement-spare.

In some cases, that's not always a great idea.  Consider the situation
whereby a remote "site" served by a remote switch has two or more
network devices that rely on another in a local fashion... such as in
the case of a NAS or SAN serving a local workgroup of machines.  If you
have to take down the central switch for whatever reason then you cut
power to the remote switch and all the associated end-station lose local
network connectivity as well.

Of course you can always resort to manually plugging in the remote
switches.  Can those GS108T-200 perform auto-cutover to AC power?  That
would be ideal.

True.  Leo's point of being able to centrally provide UPS has

I think the form-factour is already there.  I have a Motorola Atrix
smartphone.  It's available with a laptop-dock unit.  This is
essentially a USB hub and display.  The display is connected by
outputting from the phone's HDMI port.  The rest of the input/output
device (keyboard and trackpad) are seen as USB connected devices and
interfaced via the phone's USB port (Atrix supports USB host mode).

Essentially, this laptop dock is what people are talking about except
for a generic host instead of for a phone. We would want to expose the
HDMI input generically and probably with an additional VGA input.  Of
course there are also VGA-HDMI converters.  Anyone wanna ring up
Motorola to see if they're interesting in adapting the Atrix laptop-dock
technology?

Actually, this situation is as if you bought a low-end car that claims
it can go 60MPH just like a high-end sports car which also claims to go
60MPH.  But when the low-end car fails to achieve 60MPH and in fact
blows up when you try to reach that speed, you do have grounds to cry
false advertising.

According to the spec-sheet pointed to by the OP:

"GPON Rx
- Downstream data rate 2.488Gbps"

So the fact that the device fails to survive much less achieve the
claimed rate is, I would expect, false advertisement... especially when
the manufacturer acknowledges the discrepancy and refuses to take
measures to remedy the situation.

At this point, the OP may be at risk to his customers as well so it
would be really in his best interest to pursue this as far as possible
which may include legal action.

No.  Public IXPs will provide an address space for its participants to

I'm assuming you are talking about routes exchanged via a route-server.
Most moderm deployments of RSes do act transparently but in the past
there have been cases where some exchange point participants did want to
see the RS' ASN in the ASPATH.  Merit's old RSes had the capbility to
turn on or off transparency on a peer-by-peer basis.  I am not sure
about modern RS implementations.

That is a matter of personal reference and religion.  But in my

considered secondary and less preferred.

IPv4 multicast and IPv6 unicast seems standard in modern IXPs but I'm

I've looked at various inline power monitoring appliances solutions and
honestly, most of them will cost more than a small UPS.  The question
is, where do you want to monitor the voltage?  At the input side of the
rack-PDU?  Are your PDUs manageable?  Do you want to monitor voltage to
each device (output side of the PDU)?

Or do you just want to sample monitor on the side (as opposed to inline)
and fed from the same circuit feeding the input side of your PDUs
assuming all your equipment/PDUs are receiving the same power quality?
I monitor at the UPS for my home systems.  My UPSes are APC brand.  A
SmartUPS 500 w/Web/SNMP card will run you about $350 to $400 and you
poll them for input voltage and frequency.  Here's a snapshot from a
couple of years ago... I do have dirty power.

Well, yes.  Obviously it is meant to highlight the roles of public
exchanges.  That much is obvious.  And given the source of the
production it would seem to be expected.  It did touch on private
interconnects although you're right to point out that it doesn't weigh

But in a 5 min video, I wouldn't expect it to nor would I expect it to

I have similar anecdotes... and I was on the side of running the
route-servers.  This gets to be a tough nut to crack especially if you
happen to have multiple RSes on opposite ends of a layer2 failure (a
case where intended redundancy resulted in unintended new failure
modes).

The best solution we came up with at the time was to add some control
knobs to rsd in order to allow us to quickly take down the BGP session
to the peer on the falsely advertising RS.  Figuring out which
third-party negotiated "pairwise peering" was being effected during a
switch fabric breakage was done manually at the time and not all that
accurate nor of course was it expedient.  We attempted to automate that
part without too much success.

Sorry... this was poorly worded.  We did not actually tear down the BGP
sessions.  I should have placed quotes around "BGP session".  What we
did was virtually nuked the "view" in the RS of the pairwise peering
thus forcing a BGP withdrawal to the effected peers of the RS and
hopefully leaving only valid third-party views intact.  Again, the
greatest problem was detection and modeling.

Say it brother!

The fact of the matter is that by and large, the operator community not
only ignored IPv6 but many poo-poo'ed it and diminished any amount of
support for it from the small contingent of those who were willing to
progress its deployment.  In the past there were claims that it was
immature and flawed but for the most part no one really wanted to commit
themselves to putting up or shutting up.

Meanwhile clued and semi-clued users watching from sidelines could do
nothing but play in a vacuum and yell in frustration as their providers
ignore them as well.  I speaking as a demoralised user personally gave
up begging my provider for IPv6 connectivity.  Yes, there's always
tunnels but that's not the answer for real deployment.  Remember how
well tunnels worked out for multicast?

As a result, we are in a situation today where we are now scrambling to
do the things that should have evolved naturally.  Worse than stale code
is stale procedures and the lack of long-term growth and embracement.

What this means is that while we once could have taken the chance and
deployed a less than perfect technology, gotten early adopters and
slowly progressed mass-adoption, we are now in a position that we have
to undergo a crash-course in training and operational procedures.
Beyond that, the user community will need to be educated and even more
effort will need to be made in order to make things user-friendly.

And because of the heightened need for more modern features as well as
security, I might argue that we are relatively less prepared in our IPv6
development from a software standpoint than during the infancy of the
protocol.

It is often much easier for everyone involved if you slowly raise the
bar rather than suddenly springing an Olympic level high-jump upon them.

Because in some organisations, the only vendor that matters is Cisco.

It exploded and was destroyed during construction.  Parts of it were
also recycled to build the next CRS. |8^)

Come now.  You know the answer to that.  While technically true, by that
logic, Cisco should never perform any press releases.

Again, that may be true but I think you give marketing in general more
credit for credibility than actually exists.  Pathetic or not, it
happens and some people don't actually see it for the blatant undertruth
that it is... especially those who have been blinded by the Cisco
"light".  We in this industry often forget that not everyone looks for
dotted T's and crossed I's when it comes to detail.  For whatever
reason, most people don't directly challenge the spindoctors.

If IPv6 is being mentioned in mainstream news media including local and
national TV news (which it has) then I would expect a salesperson of an
ISP to also be somewhat knowledgeable enough to be able to able to at
least spell it.

And I agree with the previous poster that in this day and age, it is
unlikely that the sales group of a global provider would not have
encountered such a request.  If anything, they should have been hit with
those kinds of requests starting ten years ago.  Perhaps that particular
salesperson had not but he/she should have been briefed on it and should
be familiar enough with deployment status to be able to talk
intelligently and honestly with a potential customer.
