East Coast Datacenter

February 18, 2007 6:49 pm

I’m pleased to announce that in addition to Fremont, CA and Dallas, TX datacenters, we now have machines located in Atlanta, GA. There are a few more details on the “[url=http://www.linode.com/products/network.cfm]Our Network[/url]” page. For latency comparison, you can ping 64.22.71.1 .

Please open a support ticket if you’re interested in migrating to that datacenter.

  1. Hi Chris,

    It really is nice seeing Linode.com expanding out even further at your typically cautious rate :-).

    Nice — from AMSIX (Amsterdam):

    105ms … AtlantaNAP
    160ms … HE.net Fremont

    Would migrating help with max bandwidth? The best I ever get when downloading from Fremont is round 200kbyte/sec. A test this morning (UTC) got me an average of 183kbyte/sec downloading a 30MB file[*]. It will definitely be worth the trouble if Linode/AtlantaNAP can improve on that.

    [*] For comparison a few minutes later I got an average 1.28Mbyte/sec from kernel.org — max 1.96 Mbyte/sec, the top-speed of my ADSL line.

    EDIT (Feb-22): After migrating to the Atlanta DC, my download rate improved by more than 35%. The same 30MB file downloaded at 250k/s average (254k/s max).

    [i]Hopefully it doesn’t degrade over time.[/i]

  2. Great news!

    I assume this will require a change of IP?

  3. I thought about migrating to the West Coast data centre a while back, since it’d be closer to the fibres to Australia. Thing is, it’s 20-30ms less ping, so not worth the effort.

    Besides which, one of these days everything West of the San Andreas is gonna go kersplash and become Arizona Bay*. Better to be in Texas then, I reckon, though I suspect it might not do good things to connectivity to .au

  4. From Australia, ssh session from Fremont is slightly faster than Dallas, but both are quite useable – I’ve got slower responses from some of the older boxes on my LAN!

    And The Big One is more likely to hit Southern California, from what I read last – may not affect Hurricane Electric too much.

    Yup, since you’d be changing to a new data center.

  6. Is this the major announcement hinted at within the RAM upgrade thread?

    No complaints, just wondering.

  8. tasaro,

    I haven’t had a chance to say welcome, and how it’s nice to have another Linode staff member to help us out around here.

    I’d like to suggest that you pick some distinctive avatar for the forums. We can all recognize Caker and Mike at a glance. My first reaction to your post here was "why would this guy know anything about it" until I caught the "Linode Staff" by your name. An avatar we could recognize would really help us to know when we’re seeing an "official" response.

    Edit: Funny, mine’s not showing up on this post, and I can’t go look at my profile without a prompt. Maybe there’s some problem with the forum at the moment, and if so, please ignore me!

  9. Hi,

    I just migrated my bundle of images to Atlanta. SSH’ing feels a lot snappier than Amsterdam<->Fremont.

    FWIW, for others who are thinking of migrating their Linode(s), here are some of the notes I made:

    * See Aaron’s post about [url=http://www.linode.com/forums/viewtopic.php?t=2625]"Filtered ports at new datacenter"[/url].

    * Prior to starting migration, set TTL in DNS to a low number for affected domains (Zoneedit.com permits a TTL 1200 [20mins] under "Configure SOA"). Ideally, wait for old TTL to expire before commencing the migration.

    * transfer rate — between 0800 and 1000 UTC — Fremont -> Atlanta was roughly 40-50MB/min (1GB ~25mins) .

    * disk image transfers are uncompressed, so shrink underutilized disk images to speed up the migration.

    * New hosts are Ubuntu-based
    (Linux hostXX.atlanta.linode.com 2.6.16.36-2-bigmem #1 SMP Tue Dec 26 13:58:52 EST 2006 i686 GNU/Linux).

    * Reverse DNS and authorized keys have to be set again.

    * After migrating, set TTL in DNS SOA to a more reasonable number again (e.g. 8600 = 1 day).

    [EDIT: Feb-22]

    * Replaced http://ftp.us.debian.org in /etc/apt/sources.list with http://ftp-mirror.internap.com/pub/debian/ — a mere 3.2ms ping time away. This source also mirrors Ubuntu.)

    I assume that’s a typo for 86400 = 1 day?

    Yes, you’re right. Thanks for the heads-up — I had in fact repeated it in my DNS. 😳

    Now set to the proper number for one day: 86400

    Cliff

  12. Caker, could you please put a test file on a server in the new datacenter, so I can test the download speed?
    I live in Belgium and want to see if I get a higher speed then on host 44 where I am now.
    There is not much difference in the ping (now: 126 new DC: 111)

    It is about 64ms quicker from London to the East Coast (124ms) than the West Coast (188ms).

    This is good news for European customers..!

  15. Thanks for your notes c1i77, they were very helpful.. I have now migrated from Dallas to Atlanta without a hitch (thanks Tom!). Here are a few notes to supplement the ones above..

    The new hosts seem to be about twice as fast as the old Dallas hosts, judging by the significant drop I’ve observed in the dashboard CPU graphs (my Linode is still running exactly the same services and under the same load).

    It is a good idea to run a grep on your entire /etc directory for your old IPs before migrating. I had bound a number of services (apache, mysql) to specific IP addresses and had also configured manual networking – all these things needed changing.

    The filtered ports at Atlanta are an issue. Be sure to check the [url=http://www.linode.com/forums/viewtopic.php?t=2625]list[/url] before migrating, and remember that they apply to both incoming and outgoing communications.

    Last (and probably least), there don’t seem to be any nameservers provided by Linode at Atlanta, the nearest being at Dallas (only 30ms away anyway). I guess we could use public ones instead but I have yet to look for any of these.
