Suspected DOS attack against certain sites.

I am having a problem accessing certain websites, they are:
www.securityspace.com
www.friendster.com
www.blogger.com

I'm trying to investigate if any other websites are affected. Other sites affected:
www.bbc.co.uk
SST 9:18AM:
www.sgforums.com

When trying to access the above-mentioned sites, firefox returns a strange result:
http://[www.:0.com]/actionpage?basi...asondata=&replayhash=246gYnNaKykurw/7ZFCMTQ==

Internet Explorer 7 says IE cannot display the webpage.
I can't find any problem on my computer at all, can someone enlighten me about the strange result? What is that www.:0.com?

Those websites seem to be under a DOS attack. Can someone please help me check them out?

 

I have no problem accessing them. They load fast enough. Both in Firefox and internet explorer

 

They load fine here using Opera.

I really don't know, but what is that :0 thing in the address doing??
Take a look at this part of the address when I try visiting those websites!

Thx for adjusting the margins.

 

Are you being blocked for some reason?

Rmus, I have absolutely no clue as to what I am being blocked by or whether I'm even being blocked!. Of course I wouldn't block myself at all!

Now tell me, do you find it funny that I can't access a innocent news website such as BBC! Why would I/why should I be blocked by some unknown object for no reason at all? And what the hell is www.:0.com

I even did ipconfig/release and ipconfig/renew and the DHCP server assigned me a new IP address instantly. But I still can't get to those websites!

 

No, I don't think it is funny at all; I wasn't implying that.

I saw "block" several times in the URL you posted and that is what occurred to me.

I didn't see BBC before in your post.

I assume there are some sites like Wilders that you can access.

Were you able to access BBC or the others earlier today?

If so you might clear all your caches and check again.

Can you phone your ISP?

Or Find someone else that uses your ISP and see if there is a similar problem?

I'll check with those guys using the same ISP as me.

 

Try the numeric for friendster.com:


http://209.11.168.201/

It does not work. Same result.
It is now occurring to me that only certain websites are affected by this. Including some proxy sites.

 

I have a note about www.:0.com having something to do with Proxy, but no further explanation. (I don't have proxy)

I'll check some more.

EDIT: that is a false alarm.

It sounds like either a routing problem or something with your ISP. You might try doing a traceroute to those sites as well as sites that you can get, see if there's a common server showing up in the blocked sites' traceroutes that are not showing up in the sites you can get to. Next I would check the DNS servers (try the OpenDNS servers: 208.67.222.222 and 208.67.220.220). After that I would say your internet software (try disabling) and as Rmus suggested, call your ISP.

 

Update: All is ok now. The websites can now be accessed.
Thx to all who offered their advice and suggestions.

 

And how did you fix it?

I did nothing. I just waited for a while and the websites could be accessed. Anyway, everything's back to normal.

 

Network issues, either DNS or connectivity. We get similar things at work, even with our intranet which spans our WAN (nationally).
