Operations Issues

• Still transfer problems with SL5 disk servers. lcg-cp works but lcg-cr doesn't for ATLAS
• LHCb is still throttled
• testing gridftp-internal externally showed that there is a configuration problem in the site firewall causing some transfers to fail
• There are transfer problems to a new batch of disk servers at NDGF affecting only RAL

PreProd

---

• Wrong firewall settings are preventing a number of new (ssv06-***) disk servers transferring externally

Blocking issues

• Any ongoing production problems at present will jepordize the timeline for starting 2.1.9 upgrades at the end of this month.
