| [ Brighthouse] Slowdowns in Tampa Bay???
Folks anyone else seeing significant slowdowns after about 5pm in the Tampa area. During the day I see close to 5000kbps downstream and 329 kbps up. Gets to be about 5ish and everything goes downhill in a hurry. Only the last few days have I noticed it. RR says the line is fine and gave me the slow browser line I saw them give someone else here.
thx

Yes, I noticed the same thing...for the last three days, when I get up in the morning, I'm getting my 15mb down, and after I get home from work around 5pm, the connection drops to about 2-3mb down. The interesting thing is that "local" connections are still 15mb down (i.e., roadrunner's binary newsgroups, and rr's speed test), but it's connections to the "outside world" that slow down considerably. Also I've noticed each morning a "local area connection lost" icon that appears in the tray on the bottom right of the screen; perhaps somehow the connection is being reset each nigh.
I called BH about this other day, and they couldn't find anything wrong, even though I had the tech guy run his connection on the speakeasy broadband test and he maxed out, while I was getting only about 2-3mb down. |

| Yeah it gets so bad my ATT Callvantage service starts dropping my calls on my IP phone. It's very predictable, starts ramping up just like you indicated. I have seen my rates drop to 400kbps/11kbps. Just maybe they should invest in a few more Cisco CCIE folks huh. |

| Man I'd love to see 400 kbps down right now! How are you folks getting such great speeds? Yes it's not what you ordered, but look what I get:

17880 bits per second! This has been going on for 4 months now. At 6 am it'll be 5,000,000 bits per second. From 6 pm to 1 am M-F and 1 pm to 5 pm Sat and Sun, it's like this. My node is obviously massively oversold, but Brighthouse doesn't give a crap. I can't get DSL, but as soon as FIOS is available, I'm switching (Verizon installed fiber along my street last month). I have the $70 a month Virtual Office "Business Class" service.

got home today to find things at full speed. Maybe because it's Friday and the start of a weekend. Once again, I saw two "lost connection" icons in my tray. |

| I've had Roadrunner since March 1998, the first 1 1/2 years in Clearwater and the rest in Brandon. Only 6 months out of all those years have they actually delivered their advertised speeds to me- March 2005 to September 2005 was awesome. Surfing experience felt the same as the T1 at work. Now it's back to the same old crap. 50% packet loss during peak hours. T1 costs way more. You get what you pay for I guess, yet how come others see great speeds? I look at some of the people complaining about *only* 2000 kbps down. Damn. Wish I was them. Brighthouse tech folks- I hope you are reading this. I rarely complain about anything, but frankly, I'm fed up. FIOS here I come!

I ran the test at 1 AM and 9 AM today. At 1 AM it was 6.7 Kbits/sec down. At 9 AM it was 4.7 Mbits/sec down. Here's from a few minutes ago:

On the following link, everything looks pretty good except for one site, se.biz.rr.com in Valrico, showing packet loss at about 20%. Guess where I live? About a mile from Valrico..

| Can someone deciper this? It looks to be about the same packet loss on each hop. Would this be caused by my node being overloaded? Or are there issues with each hop?

| Last Monday evening packet loss was around 90% (I gave up and watched TV..), but as of Tuesday the packet loss has totally stopped. Peak time speeds are running about 350 kbits/sec, which is *flying* compared to before. Web browsing has improved tremendously. Nothing times out and generally feels quick.
Can a network guru here answer a question:
What causes packet loss when a node is overloaded? It is because the headend router on the node doesn't have sufficient memory to buffer the requests? Think they added memory to the router on my node? |

| Found the answer on Cisco's site:
"A common scenario for packet loss is when an output queue is full of packets to be transmitted where there is no additional memory space for additional ingress packets; this condition is commonly referred to as an output queue full condition. In this condition, the network device that is queuing the packets has no choice but to drop the packet. For example, an output queue full condition can occur where a sender attached to an interface of a higher speed is sending to a receiver attached to an interface of a lower speed. Eventually, the output queue buffers become full, resulting in dropped packets."

I don't know if that's what was happening, but I'd bet it was, and some nice Brighthouse tech saw my post and investigated (Thank you!). |

I smell a router problem due to all the traffic from the extra speed. Try Pingplotter, it gave me the tools I needed. I'm on the albany circuit and was doing horribly. I managed to get the router companies pushed to fix their stuff. The problem wasn't actually RR. It was the routers that carry their traffic to the outside world. I see ATDN in there and bet some of your connections use level 3. RR has both carry connections off first hop. Both were bad here but since my push, down from 30-90% packet loss to max of 6 on servers around here. above.net is terrible, but unfortunately they are not direct carriers of RR's connections, at least here. So the websites in question need to take it up with them. Unless you're an extremely influential person like Donald Trump :P Pingplotter should help see where the problem lies without manually pinging each one you did tracert on repeatedly and you can save graphs and results to e-mail them, as I did. Good luck. |

By the way, were these pings done not under load? I don't like some of the max you're getting from some of RR's routers. I am not from Pingplotter(you may think with how much I recommend it) but use it. It can provide you with Vital data this doesn't and you can save it to use later. The idiot test RR may have you do is no good, it just measures packet loss at a server, but not on path to the server. Each router will usually retry a packet on route to destination, thus you're seeing loss of the destination eg yahoo.com, not from ATDN or Level 3. Pingplotter shows the loss of whole path by gathering data on each individual router. 30 day free trial of the good version! More than enough to find the problem. |
