Slow Forums: PF Under DDOS Attack

[Lancelot59]

Actually, I'm pretty sure it's a proportional font thing.
I've been trying to take the image, drop it in CODE tags, and remove the dots to see if that fixes it, but no joy yet.

Are you using a replace function to replace all the periods with spaces?

 

[nismaratwork]

omg, the moment you said that I looked back and now it jumped out at me.

I swear, all I could see in it was a nasty squid-skull thing crawling across the screen on stumpy little tentacles.

You referenced Lovecraft, all is well.

 

[DaveC426913]

Are you using a replace function to replace all the periods with spaces?

That was the idea, yes.

 

[AlephZero]

When you (student) have been up all night punching cards and waiting for your output to debug, those last columns don't seem too important.

Try editing input data on paper tape, and then watch a high speed tape reader "stress-test" your splices.

Punched cards were for wimps.

 

[AlephZero]

Snoopy calendars and Playboy Playmates in ASCII art on the line printers. Those were the days. :!)

And writing programs to make the line printer play the William Tell overture. (Or the "Dick Barton Special Agent" signature tune, in the UK).

Dada dum dada dum dada dum dum dum [repeat 3 times] dada DRRRRRRRRdadada dum dum dum...

Never spliced paper punch tape before. Dang, I must be a wimp.

 

[fluidistic]

Some pages won't open, others will do within 5 minutes for me. Strangely I can reach PF much faster than days ago.

 

[Borek]

Several minutes ago I got 502 Bad Gateway error - I believe that's the same one I have seen when DOS attack started. Luckily seems like it was temporary, it stopped right after I contacted Greg to tell him something is wrong, but I guess it may be worth checking.

I was able to access other sites, so it wasn't on my side (or at least it wasn't close to me).

 

[Greg Bernhardt]

Keep the updates coming. Thanks

 

[DevilsAvocado]

Several minutes ago I got 502 Bad Gateway error ...

We are on the same side of the lake, and it looks pretty OK for me, almost as fast as google.com in SF...

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.

Yes intermittent here too. Sometimes prompt and sometimes nothing

What!?

Do you have dial-up?

What!?

I use tracert.org. I didn't save the pings, but here's a traceroute.

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... )

 

[turbo]

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.

 

[Borek]

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

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.

 

[DevilsAvocado]

... 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??

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)

 

[Jiggy-Ninja]

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

That's an interesting "typo" of typo.

 

[Borek]

That's an interesting "typo" of typo.

Yep, I wanted to correct it, but it was already quoted.

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.

I'll bet you it's the Koch brothers. They're behind everything nowadays.

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 haven't had that issue come up yet. Haven't visited the site using windows for a while.
