broadband blocking legitimate websites?

[Nicholas232]

Hi all,

I have noticed that in the past 2 weeks I am not able to access through my broadband some of my work (university) websites. Initially I thought that the websites were down. But then I checked through mobile data (another company, not sky) and it was working fine. I have asked my employer whether for some reason they block outside IP addresses and they told me that they have heard that providers like sky and virgin sometimes block the address (!). 

I have tried explicitly to remove the shield, and then to include it explicitly to the whitelisted addresses, but without any success. 
I am wondering why this happens? An example of a website that I have lost access the past few weeks is:
https://tulip.liv.ac.uk/ 

what happened and the access was lost a few weeks ago? Any information on that is highly appreciated. thank you very much.

Kind regards,

Nicholas

Have you  changed  the age settings  on your  broadband? That may be the reason for it

Dear P-C Marlow,

thank you so much for replying!

no I haven't changed anything. I have also explicitly whitelisted the site and it made no difference. I tried to remove completely the shield and again it didn't make any difference.

Kind regards,

Nicholas

Update:

I tried it today and somehow the access is restored. I didn't do anything in particular.

Either the whitelisting takes 1 day to apply. I doubt that since the instructions say otherwise.
Or something else changed independently of my router/connection.

thank you anyway for the help.

Kind regards,

Nicholas

Hi,

I have an update on this topic. So apparently what happens is that sometimes, apparently randomly I do not have access to these websites and some other times I have. On Sunday I had no access, yesterday Monday I had. Today I had to check and it looks like I don't have.

The website is up, there is no issue and it looks like that half of the time I have no access.

Has anyone else has seen such a thing before? Is this some issue with Sky? or something related to the fibre network somehow? thank you!

Kind regards,

Nicholas
