    routing to EU west changed again? Its like before the maintenance now again..., used to be like in (seconds creenshot) here for the past 2 weeks: http://dev.dota2.com/showthread.php?t=137561 and now its again using interoute instead of cogentco (like the first linked screenshot).

    Is it because cogentco is kinda overloaded in the evenings? (cogentco was adding a lot of ms in the evenings)

    Lightbulb Level3 link congestion?

    Dear Volvo,

    Each time I encounter the strange lag spikes, i always try to grab the IP and verify what I am experiencing via another means besides Dota2.

    Almost each and every time I have checked over the last few weeks, I notice that generally I start to see the same IP address showing up, and it is continually the source of delay for my particular case (or ISP, Brighthouse in Central FL).

    Anyway, after locating who owned the IP, and then finding Level3's looking glass, here is my results from within their own network.....




    I would guess something is up with that link (DDOS, OverSubscription, etc), but either way, this has been consistent during this laggy period.

    Steam servers have huge problems... I have lag 180-45 ms 45% LOSS!
    Usually I have 10 ms 0% Loss.

    What's going on?!

    Server problems on Europe East or West!
    This is how Dota2 games should look like! Game 1_Game 2_Game 3_Game 4_Game 5_Game 6

    Milton, what happened to the DE-CIX link with EUW? Why am I being routed via AMS-IX? My ping is twice as high now.

    My IP is 195.88.14.241 (AS48084), Ukraine.
    C:\Documents and Settings\user>tracert 146.66.152.150

    Tracing route to 146.66.152.150 over a maximum of 30 hops:

    Here is traceroute from the last week:

    7 * * * Request timed out.
    Also, can you please force traffic to my ISP so it gets to me via Datagroup (AS21219) and not TOP NET(AS21011)? I think you should have that route available from your side either via Level3 or DE-CIX. It will bring my latency down to like 43 ms. Though, they have the same problem now with the AMS-IX peering being active instead of the DE-CIX one. Something happened in the last few days wich has screwed up a lot of ukrainian ISP's routing to Valve. Look into this please.
    Thanks.

    DE-CIX suboptimal routing to EUW

    To my previous post, it seems that my ISP has switched to Datagroup (AS21219) for accessing DE-CIX and AMS-IX, ping is a bit lower now. But they have the same problem with the AMS-IX route being active instead of the DE-CIX one. Something happened in the last few days which has screwed up a lot of major ukrainian ISPs' routing to EU west (Datagroup, TOPNET, UARnet, Ucomline, Wnet, MTS Ukraine). Look into this please.

    My IP is 195.88.14.241 (AS48084), Ukraine.
    Here's my traceroute now:
    Code:
    Tracing route to 146.66.152.150 over a maximum of 30 hops:
    
      1    <1 ms    <1 ms    <1 мс  router [192.168.1.1]
      2     1 ms    <1 ms    <1 ms  10.90.0.92
      3     1 ms    <1 ms    <1 ms  ip9-131.200.109.crimea.com [109.200.131.9]
      4    13 ms    13 ms    13 ms  46-164-158-149-static.datagroup.ua [46.164.158.149]
      5    40 ms    40 ms    40 ms  ae22-454.k90.fra.datagroup.ua [80.91.160.158]                          <===== Frankfurt
      6    64 ms    65 ms    65 ms  80.249.211.23                                                          <===== AMS-IX
      7    62 ms    62 ms    62 ms  146-66-154-226.valve.net [146.66.154.226] 		  
      8     *        *        *     Request timed out.
    The fifth hop is in Frankfurt. Instead of going straight to Luxembourg via DE-CIX the route leads to Amsterdam.
    The sixth hop is Valve's AMS-IX connection which adds unnecessary +20 ms to latency.

    I can't dig into Datagroup's paths because they give limited access to their looking glass, but TOPNET's (AS21011) bgp router in Frankfurt shows that they choose AMS-IX path based on its lower metric (2 vs 30). I imagine similar thing is happening with Datagroup since they are basically the same company.

    Code:
    Router: br01.fft@WORLD (Kleyerstrasse 79-89) 
    Command: sh bgp vpnv4 unicast vrf WORLD 146.66.152.0/23

    Hey valve, can I ask WHY the fuck does nearly every game I get into, some asshat doesn't connect to the game? This shit has been going on for a few hours and needs to stop.

    Ok, not sure what's going on, but my ping in-game is getting worse and worse... Pinging the US East server I get ~40ms, while in-game I used to have 60-80ms... Now it's up to ~100-110ms.
