    DV2 upgrading again ?

    Hi folks,

    Anyone here with DV2 having problems ? My site just disappeared and dv2.net are down too - this happened a few days ago, something to do with an upgrade and wondered if it's happening again. I got an email from them this morning saying that the downtime the other day was for routing upgrading and my server shouldn't go down again, but less than 12 hours and it's happened again. If this is an upgrade it would be nice to be told in advance as I've customers here wanting to know what's happening and they know as much as me lol

    Yes, they are upgrading routers. We went down for about 2 mins and came right back up. The one they're working on now seems to be giving them a bit more trouble than the last.

    However, do a traceroute when they are done...it's not williams and verio yet, but the 'Netrail Hump' appears to be gone. w00t!

    Yes, It's an enormous improvement.

    I've been sitting here with a huge grin on my face running traceroutes and cursing at Cogent's crappy peering with ATDN...now I know what it feels like to be Netdude! (j/k)

    I was told 24th? Maybe the second line is the 24th.

    Here is the email we got from eservers:

    Dear Valued eServers dot Biz Customer,

    In an effort to provide our customers with the best possible hosting experience, DV2/eServers will be performing network upgrades on the following dates:

    September 19, 2002

    All maintenance will be performed around 10 PM EST. This will ensure that any network outages experienced during these maintenance periods will have a minimal impact on our customers.

    During this upgrade we will be performing a couple of card additions and swaps on the core routers as well as migrating some users to one of the CISCO 4912's.

    No-one should notice any downtime apart from certain route changes for about 5 minutes.

    Should you have any questions regarding this maintenance, please direct your questions/concerns on the support desk located at http://support.eservers.biz/

    Please do not reply to this email.

    As always we appreciate your patience and understanding as we work to improve our services.

    Regards,
    Network Admin
    It would be nice if we had a few days notice, but I guess this is a special curcumstance.

    ...does this response i received from support at one of my providers tie in to the netrail question?...

    "...we have had reports of inbound traffic not being able to reach the servers due to congestion at Cogent..."

    ...snippet from trace: Analysis: IP packets are being lost past network "205.215.2.0" at hop 11. The route has changed so the next network at hop 12 is unknown...

    lol...

    well... cogent has done it again... out here... the cable modem company... shaw cablesystems... well... they used to peer with cogent in a lotta places... seattle, chicago and washington dc... the dsl company (primarily telus internet) buys transit from metromedia in a buncha places too (chicago, ny, seattle)... well... the cable company... their network just went to hell a few days ago... i always get ~150ms pings to chicago from dsl (which is a different story altogether... its cuz of a connection glitch or something between cogent and metromedia cuz the route itself is good) ... cable atleast used to be 60ms... (cuz of the direct peering in chicago)... well... now... its >160ms... shaw dropped all their peering except in washington dc... which means... even if i have a site hosted on cogent on the west coast... say san fran... the data goes from the west coast, to the east... back to the west...

    i m seeing that a lot more lately... peering partners want to get out of their peering with cogent but can't legally violate their agreements? so they just make it unfavorable for cogent?

    i dunno... needless to say, the cogent network itself is still great... damn those monkeys behind the routers, if they could only get their peering done right... they fixed their routing tho... routing seems sane now...

    ...my sympathies to you... the server i have there is for testing | learning purpsoses only... not one real customer, three test domains... i was just about to add twelve customer domains, and was locked out...

    ...from this experience, i've concluded that there will never be a real customer on that server...

    clarification

    someone submited this ticket on the tranxact ticket system for a server at Dragon networks (server host) with the block listed above - this is not on the DV2 network. This is acrosst he street in Glboal compass - if you have had 6 hours of trouble - you should open a ticket with them online .

    I was wondering where all this dragon network stuff was coming into a DV2 thread at. Had me confused so I just stayed quite.

    As far as DV2 the data center accross the street from Dragon things are good, servers online and downtime was nothing more than a momentary blip.

    From Techs:

    Here is what happened. It is a truly honest mistake made by DV2.



    A while back Dragon loaned DV2 some IP space, the block 209.124.80.x/20 I believe is the total block.

    Anyway, they were removed from the configs about a month ago and all customers were moved off of that block.

    Last night around 12 DV2 installed a backup RSP (processor card for their router). It had some old configs on it, so it began to announce the block of IP space that you were on and having difficulty with. So basically, two networks were announcing the same block of space to the same provider….that can’t happen, If it does, what happened this morning, is what happens.



    So, I had a time trying to get in touch with someone over there as the night time guys aren’t the network guys…this morning they removed the old configs and all cleared up.



    Sorry for the inconvenience. It was a freak occurrence, since we had loaned them space a while back and it was on that old configuration.





    It is not likely that this will happen again. Most providers have route filters that keep stuff like this from happening. Only difference here is that Cogent was accepting the route from DV2 because they had been using it due to our loaning it to them.



    Sorry for the problems.

    yes it is... but its definately not the case outa vancouver... i'll get u some traceroutes outa here... heh

    [edit]

    just noticed something... cg = calgary... very close to vancouver... well... closer than chicago is... the route should have gone up the west coast, not up central... i think the reason the routes from here to cogent are going thru DC is cuz peering agreements don't really let transfer be all that asymetrical... usually there are limits by how much the ratio for incoming vs outgoing transfer on a peering feed can be... and cogent of course is kinda one-sided... with all the webhosts/etc using them... 111ms is really pathetic... in a case like that... from sfo to calgary... i wouldn't expect anything more than 40ms... maybe 50 on the very high side...

    I have 2 servers with Dragon and I doubt the SLA is valid in this case as I don't really think you can class it under a network outage. This was totally out of their control, thus I think you can forget about getting a discount.

    Yes, one of my servers was affected, but it only has one site on it at the moment, so I don't really care about the downtime. I did phone them to ask what was going on. Three rings and a tech picked up and politly answered my question. The thought that tech support is actually available as promised makes up for this little 'accident'.

    Lets get back on topic, this is NOT a Dragon Networks thread, if you want to talk about Dragon, open another thread.

    My favorite traceroute yet. While I'll only credit eServers with the last few hops check out the route taken from a cablemodem in Florida:

    For those without patience the packet appears to go from Florida to Atlanta, Georgia to Dallas, Texas to Los Angeles, CA to San Francisco, CA to the Netrail peer before shooting back to Atlanta, Georgia for DV2.

    And as if that's not bad enough the ATT/Cogent peering adds a nice bit of latency!

    fun with tracerts

    almost all of our traffic is outbound so - here is the real indicator of that. Not bad at all in my book.

    please post tracerts from the server out as this is the best measure of performance.
