Upload problems only at certain websites???

[redgtxdi]

OK, long-story short.....

Went to upload a pic (ONE pic) to photobucket the other day and couldn't do it. It was about 1mb and the sucker took forever & finally stalled. Next morning I got it to go, but took FOREVER!!!

Noticed same prob w/ imageshack. (timed out). Costco photo uploads just fine.

Started testing some speedtest sites for upload & got the following.......

Speedtest.net (d/l fine, upload fail.....can't even initiate)
testmy.net (upload fail mostly & occasinally eeks out 3-4kbps)
Linkline @ dslr (d/l fine, upload fail....again, takes forever *if* it initiates)

Speakeasy = all fine
Toast = all fine

I don't get it. I'm in So Cal TimeWarner/RR country & they recently had a DNS attack but supposedly that's fixed. Spoke w/ Tier3 noc at TW a couple nights ago & every single, solitary test was fine. Tried OpenDNS, RR DNS, router, modem, wireless, wired.....when I say I tried everything, I mean.....EVERYTHING......and nothing is revealing what the deal is.

Well, I don't think I can tell you what it is, but I can tell that it is not DNS related. Once you've connected to a site, and in the process of doing a single session task, DNS has nothing to do with it.

DNS affects a web page, because it frequently has multiple components from several different domains / names, and each lookup requires a DNS query. Something like a file transfer is strictly a function of MTU, windows size, latency, and ACK time (affected by latency).

It'd probably be good to start with a tracert {destination address or name} (traceroute in *nix). That'll give you the current hop-by-hop latency.

Then run a TCP check, like the www.dslreports.com "Tweak Test" to see if you can adjust your parameters.

If you're running Torrents, stop 'em (completely, both ways) & try again.

It's possible that you just hit network congestion, try later and at off times and see if your success rate goes up.

Good Luck

First, my apologies to Scott & Jack. I frequent OT, P&N, Hot Deals, etc and when I post in a new sub-category, I'm a star for forgetting!!! Thanks so much for the replies 2 days ago while I was off in la-la- land.

Anywhooo........

Things are still the same. I did do tracerts to a few locations when I was on the phone w/ TW/RR, but all looks good. No latency over 90+ms on any hops. (weird, yes)

All settings are optimized, etc. etc.

And, yes, I agree it's probably nothing to do with DNS cuz it does it on RR's servers or OpenDNS servers, no diff. Also, does it from router, directly to modem, wired, wireless.......no matter what!!!

The weird thing is how the different sites react. Somebody on DSLR suggested there was something wrong with the test site until I explained to them that between a half-dozen speedtest sites, 3 did it & 3 didn't.

Another test I just tried tonight, was to do 2 different test sites on speedtest.net. "Los Angeles" is a "FastSoft" server and failed the upload. The "San Diego" server is "FastServ" and the upload starts up shortly after d/l finishes and shows normal results.

I'm just baffled!!

what have you eliminated as not being an issue? have you tested these uploads from multiple computers on your LAN? bypassed any other network hardware?

Tried OpenDNS, RR DNS, router, modem, wireless, wired.....when I say I tried everything, I mean.....EVERYTHING......and nothing is revealing what the deal is.

And I should say too, this means I tried laptop, desktop, as-is, with router, seperately without router-directly via modem.

When I made the call to TW/RR I knew to be "wired-only" and "directly via modem" cuz otherwise they never believe you. Even the TW/RR guy was dumbfounded.
