Some websites inaccessible

Some websites inaccessible

Over the past few months I have noted that we will lose access to certain websites. Some just won't load and other will work then stop working after 5 minutes. My research suggests that this is an issue with DNSSEC. Some of the sites do not appear to be DNSSEC compliant, but others are. I have ruled out internal security on our network. I am at a loss why this is occurring. The sites work fine on my ATT phone.

Re: Some websites inaccessible

I have found this information.  Can you check it for me?

 

lazybeescripts.co.uk

 

88.208.252.141

 

The URL is the one we can't get to.  The IP is based on a lookup at godaddy.com .

 

Thank you!

Re: Some websites inaccessible

msdadmin.  Thank you.  As the phishing site originates from this IP address, the ISP that owns the IP Range will have to certify that this IP address is no longer the source of a phishing site.  In order to clear this issue the owner of the site lazybeescripts.co.uk will have to contact their ISP ( the owners of the IP space) Fasthost Internet Limited and inform them of the issue with the current IP address, request a new one and/or verify with the ISP that they are not the source of the phishing site.  The ISP will then have to contact Comcast Security and request removal of the IP address network block.

Re: Some websites inaccessible

Very nice catch Captain_John. Another more simple consideration for unaccessible websites could be in the SMC Gateway.Firewall when the Intelligent Subpacket Detection is either enabled or disabled, depending on the website server parametric operation. Just some food for thought......

Re: Some websites inaccessible

Welcome Snellit.  We can assist with this issue.  We will need the URL of the websites that you are having issues with in order to proceed.  Also the the Comcast DNS servers are 75.75.75.75  &&  75.75.76.76.  

Here is a Link to the Comcast site for the currently identified DNSSEC issues and the issue status.  Also this link http://www.dnssec-failed.org/  is to the Comcast DNSSEC Validation Test Site.  Using Comcast DNS Servers please check the site and post the result here.

 

Thank You

Re: Some websites inaccessible

I have a similar problem.  The website laxybeescripts,co.uk will not connect. When I enter it into comcast dns lookup I get an error that says

 

[Querying whois.nic.uk]
[Unable to connect to remote host]


This is similar to the timeout error (cannot connect to host) I get when trying to connect to the website itself.

 I have tried Firefox, Safari, and Chrome. While the message varies the implication in all three cases is the same.

 When I copy and past whois.nick.uk into my browser, it is not found. However, when I use nic.uk I am connected to http://www.nominet.org.uk/ and can successfully lookup whois laztbeescripts.co.uk

 Our theatre director wants very badly to use that website but cannot because of this connection issue here at school using our Comcast Business class service.

 Note the website loads perfectly when I use my iPhone on 3G but fails the same way when routing through our on campus Comcast Business class service.

 Similarly, I can connect at  home using Century LInk service --just not using Comcast Business class service at school.

 I continue to work with this issue.  I found (using Network solutions whois database) that the IP for lazybeescript.co.uk was 88.208.252.141 which when entered in to a browser at school using Comcast Business Class services, would not connect.

 

The error was the same as before but a different host whois.ripe.net .  When I tried that address in a browser, it would not connect.  But when I tried ripe.net connection was quick and clean.

 

I am stopping here.  I can't afford more time spent on this today.

Re: Some websites inaccessible

msdadmin.   Comcast Security  determined that IP  88.208.252.141 is hosting a Comcast phishing site.  As the site is still active, access to/from this IP/ site is blocked by Comcast Security.

 

Thank you.
