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

[Sara Hills]

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,
