Slow Forums: PF Under DDOS Attack

  • Thread starter Borek
  • Start date
In summary: I'm not getting the 503 errors I was getting last night.It's Tuesday morning, March 6th, about 7:30 am EST.In summary, the Physics Forums website has been experiencing slow loading times and errors, particularly the "MySQL server has gone away" error. This is attributed to a DOS attack that occurred on March 5th and is still ongoing. The site moderators are working on fixing the issue and have contacted their data center for assistance. The attack is believed to be from a disgruntled individual or group, and the site is currently being monitored for any further attacks. The site's speed has improved since last night, but it is not yet back to

Still very slow for me for many (all?) pages. Just like when I posted on March 26 in this thread.
To reply to this thread the "Reply" button hadn't even loaded after 30 s. But there was a "reply" letters so I'm replying this way right now.

That is really weird! I just made 1000 ping with only 2 lost and Average = 174ms ...

Then I tried tracert.org and got exactly the same result as you!? :bugeye:

Is this a "U.S. thing" only??

If you run Windows it’s real easy to run ping and trace route yourself, directly from your computer:
  1. Go to the Start Menu
  2. Click "Run..."
  3. Type "command.com" and hit [Enter]
  4. At the prompt in the command window, type "ping physicsforums.com" and hit [Enter]
  5. Or for trace route, type "tracert physicsforums.com" and hit [Enter]

(Don’t paste your real IP here... :wink:)

I got 309 errors earlier this afternoon. I'm not sure what that means, but I'm assuming that I couldn't contact PF's server.

Same typo of problems here - for about an hour I was not able to refresh/read/post/moderate.

But your ping seems okay? I don’t understand... I haven’t been logged on that much today, but so far everything has worked "like a dream"... maybe it’s only temporary 'spikes'... but that doesn’t make sense to the "tracert.org experience"...

I’m lost here.

... looks like "temporary spikes" because now tracert.org is also working fine ...

EDIT:
Grrrr, now tracert.org is NOT working and the EXTREMELY weird thing is that I start 10 ping in my command window (locally from Sweden) and 10 ping at tracert.org at EXACTLY the same time and it ALWAYS work locally but FAILS on tracert.org??

WT* :grumpy:


I have to leave now, hope it all works out for you guys... or you have to move to Sweden... (don’t forget to bring a big and warm fur) :smile:

I even finally registered at FaceBook to be able to report problems to Greg, but they disappeared before I did. O tempora, o mores.

It worked for some time, then stopped, just when I was trying to post this message. I had to go away, now I am back - it works again.

Doesn't look good if you ask me.

Yesterday I got a AVAST WARNING that it blocked some sort of online threat here on PF. I was logged in and don't remember what forum page it happened on. And before I could investigate what the threat was, the AVAST warning message pop-up giving a link for information ended.

If it happens again, I'll will try to find out what it is and post here.

I just got several "Page Not Found" errors. Seems like an intermittent issue, though.

Edit - More specifically:

This webpage is not available
The webpage at https://www.physicsforums.com/ might be temporarily down or it may have moved permanently to a new web address.
Error 324 (net::ERR_EMPTY_RESPONSE): Unknown error.

Btw, I use Chrome.

Oh man. I'm using version 3.6.16 and know they will not continue to support it forever. I've got the Firefox 4 install page bookmarked for when the time comes. But now you've got me worried.

I'm running Ubuntu (Linux) 64-bit and it's not an easy install job - or at least it wasn't when I did it on the day it came out.

Windows should be fine.

Additional: Over the last hour or so, whenever I click buttons such as Quote or Reply (or any link on the forum) it tries to get me to download the page I'm supposed to go to.
