Hi,
A problem with a network link at the RAL Tier1 has caused problems for file transfers to and from Tier2 sites from around 01:30 to 08:45 last night (Thursday 22nd December). This also caused the OPS VO SAM tests to fail.
The link carries file transfer data that does not go over the OPN. Other network traffic, including file transfers over the OPN link to/from CERN & Tier1 sites, as well as other non file-transfer traffic such as accesses to the BDII and LFC systems were unaffected.
