What's broken?

    This just cropped up on a single thread, so it's probably not a huge issue, but it's weird.

    Whenever I click the Go To First New Post link (the one attached to the graphic just to the left of the thread title) on the Jewish fantasy literature thread, I get a 406 error.

    The link says
    which looks like almost every other link I can see. The issue may be the apostrophe in the word "don't."

    The error message is
    ETA: Clicking the thread title works fine, as does using the "Go to last post" graphic by the username of the last poster.

    What browser? Normally, if the server sees that the data it wants to return to the local machine is not acceptable, it sends the 406 error instead. This is usually caused by a setting within the browser. Therefore, it's not something that's broken on the server.

    Firefox 3.5.8

    I get the same thing.

    Hmmm. Just checked, and I do as well. If you hover over the icon, you get a weird combination displayed at the bottom of the browser. I'll check into it later this evening.

    Did some testing, removed the apostrophe and put it back in. Works just fine now. Suspect an extra character got tossed in somewhere that wasn't showing on the thread.

    I'm not having nearly as much trouble as I was with Chrome jamming up. Still doing it but a lot less often.

    The past few days though I'm not getting the email notifications to threads I've subscribed to.

    Check your spam folder. I just tested and I get email notifications.

    I'm not seeing anything in the email logs that indicates messages are being rejected (aside from hotmail, which I'm still working on).

    Nothing in the Spam folder. I got an email ths morning when there was a post to an older thread, but nothing from more recent threads that I subscribed to.

    Weird. I will test this during the day and let you know.

    Make sure it's still turned in on your options. I'll do some testing as well later today.

    As I subscribed to the thread regarding the Chrome/GA issue at the Chrome Forum, I received this reply from that thread. Maybe others did also.

    For the record, I haven't had any of the jam ups I was experiencing when using Chrome to access GA for some time now.

    Comment #54 on issue 3041 by bugdroid1@chromium.org: DNS pre-fetching causes frequent internet loss

    The following revision refers to this bug:

    r42181 | jar@chromium.org | 2010-03-19 22:41:42 -0700 (Fri, 19 Mar 2010) | 33 lines
    Changed paths:

    2 experiments: DNS prefetch limit concurrency: TCP split a packet

    Some firewalls apparently try to preclude a "syn flood to host" by limiting
    the number of syn's (used to open a TCP/IP socket) that are outstanding
    without having received a syn-ack. Presumably this is to prevent a user
    from participating in a syn-flood attack (which traditional sends a lot
    of syn packets, with false return addresses, resulting in no responses).

    Apparently this firewall technology has in some cases been extended
    to include UDP sessions for which there has been no response, and this
    may include DNS resolutions. Since the prefetcher currently resolves
    as many as 8 names simultaneously, this is remarkably close to the
    reported threshold of 10 un-answered connections. This test attempts
    to limit connections to 2, 4, or 6, so that we can see if this helps

    In TCP, the RTO remains (under windows) at a full 3 seconds until after the
    first ack is received. As a result, if the first data packet sent (after
    the SYN) is lost, then TCP won't resend until after 3 seconds without an ack.
    As a test, we split up the first packet into two parts (the second part
    containing only one byte). This is done as an A/B test, and we'll see
    if we get a measurable improvement in page-load-time latency.

    Finally, to get better page load stats, I adjusted the PLT histograms
    so that we record a "final" time for abandoned pages when they are
    closed (even if they didn't finish rendering, etc.). This should give
    a much more fair PLT comparison for all network latency experiments.

    I've installed 2 upgrades to the firewall since this issue first started happening, so it's possible that the firewall behavior was changed in a way that fixes this. Not sure if anyone else has run into this problem lately.

    I saw your reply to the Chrome forum Biker. That firewall upgrade may have done the trick.

    Emails are being received now, thanks.

    When I click the New Posts button, I would like to see threads that I have participated in and also have new posts listed at the top of everything else.

    Huh??? That's a feature request, and as far as I know, there's nothing available to do something like that. If you want to see the posts that you've participated in, click on your name next to any post that you've made and select "View Forum Posts".
