JSTOR has been updated to the new platform with new features that include personalisation (MyJSTOR) and searching enhancements.
Access URLs have not changed but currently JSTOR is extremely slow. Problems with access to articles are occurring on both IE and Firefox. JSTOR has been notified.
You may also notice that links to recent content state that UC provides links through SFX (goes to Article Linker). This is being fixed asap.
JSTOR access is better now
There will be a delay in fixing the links to recent content feature
