Hello,
Unfortunately /pnfs is under heavy pressure from CMS global redirector. The server load goes above 30k, which slows everything down. Everythin works, but slowly ...
We've stopped the redirector service for a few hours since yesterday, and while off everything works fine. We're trying regularly to make it work again, so if you find periods of slowness it is unfortunately unavoidable.
We'll inform you as soon as the the situation is resolved.
Cheers, The IT Team
