usually forwarding loops are caused only by networking gear, not by hosts (although I've seen a few malicios ones...).
That't the problem with improperly deployed L2 network that it fails this way (l2 networks fail open, l3 networks fail closed), I guess/. could ask around a bit and let somebody design their hosting network so STP loops don't happen.
Especially if you're running HP gear.
I can volunteer and I've got the experience and skills to pull it off;)
I found out myself that roasted beans get worse and loose their unique flavor after 2 weeks of storage, no matter what kind of container I had.
So I started buying green beans and roasting around weeks worth of beans at one go (that's around 2-4dl of greens for me). The green beans store wonderfully, I had no difference in taste after storing them for many many months.
Roasting is of course important, if you have high-quality beans I usually recommend very light roast to keep the flavor, excessive roasting is used to get rid of the beans own flavor. Very light means stop roasting almost immediately after they pop their skin.
Then comes the grinding, I used a real mill (bladed ones give you omnigrind, which basically sucks for espresso, might work for drip). The output varies according to the time of year and the humidity, I usually had 4-5 different settings in my mind which pretty much followed the seasonal changes. You could almost measure the average air humidity from the grind output:P
Worked pretty well for me, I usually mixed Jamaican Blue (lightly roasted) with Columbian prime (a bit darker) 50/50 to get the best results.
I used to live in a same block as most of the city's 'exclusive' coffee shops were. My friends constantly judged my espresso and variants way better than these professional shops (I of course took good care of my equipment, cleaning them every time after making espresso and so on...).
DWDM equipment costs like hell, and the more lambdas you want to use on your few long-haul trunks, the more you pay. A few years ago we could squeeze around 96 in a single fiber, equipment to actually use only 6 was already in millions.
So no, upgrading the core won't be cheap. It's also not _that_ expensive that they couldn't pay it right now.
...and that the installation documentation is the worst I've ever seen, the free version of the exchange connector sucks unless you start paying the commercial version, there's no upgrade path for new major releases (unless you buy the commercial version) and the program is actually so badly documented (for the users) that it makes even hardened veteran cry.
Just to mention the few immediate faults that come to my mind. Yes, I've been using and administering it for months now.
But PLEASE tell me which ISP gives you multiple real IP addresses and doesn't force you to do NAT if you want to hook up multiple devices. And I cannot use PPPoE on computers...
YahooBB has strict 1 ip policy, even for their SOHO deal, which I find really weird.
I'm seriously thinking putting a new ISP up (done that once already, getting a LIR status and some transit isn't such a big deal. IGP&EGP can do with cisco & juniper and basic servers I run already) so that people with clue can boot NAT from their homelans if they wish.
Yup, and then you have to take into accout that spamassasin uses perl. Give it enought mails per second and it will kill your system. Not so with dspam.
Also DSpam was breeze to set up on my freebsd. Just insert the ready-made shema in the database, put in some configure options which are very well documented, change the LDA in the postfix config, add an alias into alias list and you can start training.
Then the fun starts.
Start thinking large-scale. Use inoculation groups that vaccinate groups of users filters before they even catch spam. Put up some honeypot addresses/proxies that feed to your filters, further vaccinating the masses. You can even put people on different groups based on their behaviour (sales and engineering people tend to get different type of spam) and pretty soon you have quite robust system. Then you can present a nice corpus of spam for new users so they never have to train their filters from the bottom up.
I got it up with postfix&mysql-dspam-cyrus&sasl&mysql combo in 3 hours, fed first spam in 10 minutes and it detected the first one by itself the next day after feeding 30 spams. No false positives and accuracy over 99.999%. Got what I asked for, now I'm going to see how it handles 100K+ users.
Your 22ms is not that bad... but you can get it down to 10ms with fast-path. I was able to squeeze out to 7-9ms (on first hop), but then I have heavily tweaked my own dslam profile (used to work for an dsl provider).
The other thing is, that you shold really only be interested in end-to-end RTT, not the individual hops. For example, if there's cisco 4xxx series switches with SUP-3's out there, your icmp/traceroute IP packets gets processed in the processor card, not on the interface, causing an 10ms more latency to pings/traceroutes. The actual IP packets of your connection get forwarded by the interface so no latency there.
Well, I can safely predict that alot of the 12xxx routers are going to reload/have reloaded already. At least if you don't have a Juniper sitting on your core, you most likely have 12xxx series one.
And try to apply an acl on their interfaces... bye bye router:)
The 69/8 was a common source of SPAM, DoSses and other abusive behaviour. We got the block back but after re-allocation the problem arose. Accuse the spammers and abusive people of this.
Um, they make much more pr0n nowdays. We're seeing something in the lines of 5 pr0ns per every movie & game release combined.
Also, pr0n gets released in steady pace, meaning, there's no 'periods' of much pr0n like we have in game releases. What was the first release at 24th of december? Pr0n. What was the first release 1th of 2003? Pr0n....and you know, pr0n is the ultimate 'money' between nerds, and it really works:
'Me want your newest game'
'Well, what do you have?'
'I have this semi-new game, agreed?'
'Sorry, got that months ago...'
'Well, I have "Briand Pumper's Pink Pussycats..."'
GSM users in the world: 732 million (www.gsmworld.com)
_Cellular_ users in US: 70 million, divided in multiple standards
Nowthen... US will 'win' if they just nicely come along with the rest of the world? Let's do it like we will be doing it here in this side of the pond. Just phase the gsm slowly out (Nokia has a dual standard phone already) and embrace a single standard.
A wild dream for the US? Surely
A wild dream for the Rest Of The World? Erm, no. Been there, done that.
Ten times the user base is a very, very powerful financial drive for the TELCOs.
...speaks a Finn whose country has a population of 5 million and at the same time has 6 million GSM's...

You've considered using portfast on edge ports? :P
You know, it's been there for awhile...

It's about 15.2 megabits per seconds, very easily in range of single server. What's the fuzz?
So, if I read the article correctly
1) They haven't heard about IMAP and storing messages in the server permanently
2) They're using their exchange mail server (not mentioned in the article but other sources tell they went from Notes to Exchange) via POP3.
Nokia doesn't write THAT much of their OWN software, they usually just outsource it.
After the vendor fucks it up then they try to fix it, usually with not-so-good results.

I work for the company.

Put a firewall up and don't allow devices that you don't want to be seen in the internet. Problem solved.
Or make your main machine a proxy and every other device in your network talks thru it.

No, The largest yatch is owned by the Sheik Mohammed bin Rashid al-Maktoum, the Crown Prince of Dubai, the name is 'Platinum'
Allen's boat was designed by the same company btw.
I do think he has the biggest yatch in US

At some point, usually after 2-3+ years into the college, you realize that NOT ALL of the FREE BOOZE needs to be drunk.

Got one slashdot a year back, didn't even flinch. The server is 800MHz p3 with apache/worker.

And of course, it's running FreeBSD
it would be very unentertaining to point it to 127.0.0.1...
But, which company is really an enemy to microsoft hmm? I wonder if a NICE RR of Sun Microsystem's critical IP's would be in order?
Lessee... somebody creates a DDOS that attacs to an A record I control... now who want's to get some DDOS?

They're not that poor servers, and they handle the load quite easily. load averages: 0.06, 0.10, 0.08
