[Eril-l] Taylor & Francis blocking IP addresses due to excessive use

[Laura Vogler]

We experienced the same issue a couple of times last week.  First time ever receiving these types of reports from T&F.  Since this seems to be occurring for a number of us, I wonder if T&F has put some feature/protections in place.  Unfortunately, the logs aren't giving us enough information to determine from where the patron is trying to connect.

You don't often get email from martinaa at mit.edu<mailto:martinaa at mit.edu>. Learn why this is important<https://aka.ms/LearnAboutSenderIdentification>
We have experienced the same thing with T&F and with University of Chicago Press Journals over the last week. U of Chicago Press thinks the issue is on their end, but we and they are still trying to establish exactly the source of the issue. In the past, we've seen citation software causing this same issue but at least in the T&F case (where we talked with the user), that was not the case this time around.

If anyone figures out what's going on, please share info!

Hello Kenyon -

Yes, we've experienced the same thing. We've had a number of reports of on-campus IP addresses being blocked. We're still trying to figure out what the cause was/is.

I'm happy to know we're not alone!

Hello,

We received a few reports last week from Taylor & Francis that they had temporarily blocked one of our IP addresses because of excessive connection to Taylor & Francis Online (tandfonline.com<https://urldefense.com/v3/__http:/tandfonline.com__;!!IaT_gp1N!wSm7aYZLkckv-8S1C-SYwjntc5qMzp8ODu3z8wutJm7cSZGTO_AYW6G5VUdGKWibs7S8xyLzjwiA4eHfEuc$>). The activity occurs over a period of one or two minutes and involves dozens of connections to only 1 or 2 pages. The block seems to occur after 100 total connection attempts.

Our IT group investigated and suggested the activity could be due to a buggy browser. We've contacted a few users and they mentioned they were using Chrome and Zotero.

Has anyone else experienced similar issues with Taylor & Francis Online or with Chrome or Zotero? If yes, do you have any suggestions on what we can do or should investigate?

Thank you,
