Huge packet losses to Yahoo website when the rest of the Internet is OK.

[humax]

Spoiler

Hi there,
I've been expeincing huge packet losses to the Yahoo website for 2 days for some reason but the rest of the Internet works just fine. Initially I thought that it's a problem on the Yahoo side till I tried VPN with Japanese and the US IPs. So when I launch VPN with either Japanese or the US IP adderesses on the same PC the Yahoo website just flies but when I get back to a TPG IP address again the website just barely opens. Here is what my ping from the TPG IP  to Yahoo looks like :

And this is my ping to Google:

I'd like TPG staff would fix that for me please.

Hi @humax . Can you do   tracert yahoo.com   and    nslookup yahoo.com    without using VPN and copy results in your reply.

We have also been having major issues connecting to yahoo mail (https://au.mail.yahoo.com) since approx 7am thursday morning (Melb local)

have checked via all all PC's (and my Mobile using WIFI on our home TPG network) and yahoo is extreamly slow to load (firefox/edge/chrome) and near unresponsive when it does eventually open

have tested using Mobile off wifi (ie using Mobile non-TPG data connection) and have no issues connecting to yahoo and normal response) - it was only from this point I started to suspect TPG issue

Logged onto my Work network and have no issues connecting to Yahoo Mail via Work network

tracert does not show any significant issues

BTW, the Yahoo worked well just right after midnight this very early morning but now it's broken again. The ping from TPG to Yahoo seems to be normal though. But Yahoo web pages just still do not open. Via VPN it works perfect.

Thanks

[david64]

@humax . There is a delay between lines 3 and 4 (2 TPG devices) and another between lines 5 and 6.

Can you do tracert again, maybe just after midnight. It will show if delays are less or if routing changes.

It looks like the Yahoo site is working OK at the moment.

[david64]

@humax . Network times are still long, but if Yahoo is working, long response times might not be the cause of the problem. Yahoo itself might be having delays gathering all its output. It does come out very slowly; looking at Networking tab in Task Manager.

[humax]

Yahoo is dead again if via TPG. At the same time it works lightining fast via VPN with any foreign IP address. I also tried Yahoo with Telstra broadband and it's doing just fine there.  So it's 100% TPG problem.

[agee51]

I agree issue appears to be TPG related

yahoo works perfect no delay when using Mobile data connection instead of my local lan, and when I remote into the office and use office network and as Humax advises issue came good for short time via TPG then died again (I presumed at the time someone may have been working on issue)

not having issues with any other sites I visit - no issues with online gaming, network speeds are normal, only isssue I have is with accessing au.mail.yahoo.com via TPG network
