Google Scholar blocking Search via Campus Proxy Nitesh Bhatia 2/18/13 2:43 AM
Hi
In our university Internet runs behind campus-wide proxy. So internet ip of each and ever computer running on the campus is same as proxy ip. Recently Google scholar has started blocking our search queries based on the fact that it is getting a lot of queries via our particular ip. It is obvious that at a time is 1500 people are accessing Google scholar then it will get high number of hits but it becomes annoying to enter captcha every time we search.

My question is - Is it possible to submit our specific campus ip to Google so that it ignores high number of hits - due to the fact that we not bots but a bunch of researchers searching for various papers?

PS: I posted the question here coz I couldn't find any way to direct contact Google Scholar Team.

Thanks
Nitesh

Hi Nitesh,

Can you let me know exactly what you're seeing so that you know that your search queries are being blocked? It would be helpful to have an example to bring to the team at Google.

Thanks!

Hi
Let me give you a bit more explanation.

1- When I open scholar.google.com for searching it first shows a captacha check claiming that too many requests are coming from our IP. To access scholar, every time we have to fill the captcha which sometimes get irritating.

2- In our campus we have one high bandwidth internet line and all the systems inside campus access internet through this line via proxy. So all systems have same internet IPs. To my understanding, since we have same IP (via internal proxy servers) for accessing internet campuswide, scholar is bound to receive large number of requests. Hence it is blocking it thinking that its a bot-attack.


Are there any workarounds to fix this issue?

Thanks
Nitesh

Hi Nitesh,

Thanks for getting back to me with those details. One more follow up question - are you all seeing captchas on search queries on google.com as well? I'd assume that as much as people use Scholar, they're using search even more. 

In the meantime, I'd definitely reach out to your network administrator for your school to see if there is a way to set up multiple IP addresses for your campus. Given that IP addresses are typically one per user, our system will detect massive amounts of queries coming from the same one and assume that they are automated queries. If there is a particular reason that your campus cannot have multiple IP addresses, please get back to me with that information and I'll send it off to the team to see what they think. 

Thanks,
Courtney

Hello,

We have the same problem with google scholar access in our network. We use 5 proxy servers (5 different IP addresses) for huge number of users. They complain that they have to fill captcha every time when they try to access google scholar, and sometimes the access is even forbidden.
I have to point out that we've been using proxy servers for several years, and this problem appeared in the last month.
Our proxy servers are configured to send x-forwarded-for information  for identifying the originating IP address of a client, which could be used for solving this issue. However NAT is used in certain parts of our network, which can also cause sending considerable amount of queries from unique IP address.
We would be very grateful if this issue could be solved, since our network is academic network and our users benefit a lot from this service.

Thank you.

Thanks for the information. I've reached out to the Scholar team about this issue. I can't promise they'll have an easy fix for your campuses, but hopefully they'll be able to look into the issue!

Best,

Hello,

in the past few days we have often encountered this problem in our campus. The access is often forbidden and there is rising discontent among our users. I wonder, could some IP addresses get whitelisted in order to gain regular access to scholar service. Many campuses implement proxy solutions and it is quite unpleasant if they are deprived from this service.

I'm seeing the same problem with scholar.google in general, regardless of which IP address I'm using -- from home or the office or school. Sometimes I receive a link with the captcha option, often I fill in the captcha *multiple* times before I can get into Scholar, but lately I don't even have the captcha option. Instead, I'm offered a page that suggests my (various) computers are in need of a HiJackthis cleaning, which I simply don't believe, on the grounds that the scholar page is rejecting so many different computers / IP addresses.

Hi all,

The Scholar team has asked that you report these issues directly to them by clicking the link at the bottom of every Scholar results page to provide feedback. In your feedback, make sure to include the specific IP addresses which are having issues and what difficulties you're experiencing.

Thanks, and sorry for the delay here!
