Getting websites unblocked

I am back working on the revised version of Indispendable Librarian this week and I'll be sharing some things I'd like input on from my brilliant Blue Skunk readers.
I am working from the Friendship Beach Resort in Phuket, Thailand, a real hardship post as you can see from this picture taken as I started work this morning about 6:30:
I have two offices: the table and the lounge chair.
The section below has driven me crazy. I know I've written on this topic before, but I'll be damned if I can find the blog post. I am sure the original was pure genius (as most lost writings are.) Anyway, I'd appreciate knowing any strategies you've used to a website unblocked in your school that I can add to my list. Thanks.
Getting websites unblocked
There are few situations more frustrating for a librarian than learning of an Internet resource or tool that would be of value to students but finding it blocked by the district. Here are some strategies for dealing with this problem:
- Know and be able to articulate the educational value of the blocked site.
- Be able to share examples of how librarians and teachers in other districts are using the resource.
- Ask to have the resource provided on a limited basis – for a certain period of time or on specific computers. Report at the end of the test period if any problems were encountered and what uses students made of the resource.
- Speak as a member of a group that wants the resource unblocked.
- Know exactly who makes the filtering decisions in your district and if there is a formal process for getting a site unblocked.
- Know local, state, and federal laws pertaining to filtering and student Internet access to avoid “hyper-compliance” by your district.
- Communicate in writing your requests and responses when seeking to get a site unblocked. Always copy the supervisor of the decision-maker on all communications.
- Seek to establish a formal review process for unblocking Internet resources or seek to have the reconsider policy in your district revised to cover online resources.
- File a challenge on the resource to start the due-diligence process on school materials. (Yes, you can do this as a staff member.)
- Don’t give up after the first denied request. Come back with other uses, examples, and partners. Sometime the squeaky wheel gets some grease.
