*SNIP* It would seem that a power failure in the neighbourhood, however short, instantly *kills* the all services that are provisioned over the connection. Surely the building switch(s) (vector/isp?) and the rest of the network equipment (vector?) should be protected by UPS so as to avoid failure during short power outages? *SNIP* Yeah, I think that was kind of what Vector were hoping for. But a lot of their terminating switches are buried in basement rooms to which only the building manager has a key. I know that we had quite a few instances of banging heads on walls trying to get access to put our kit in with Vector's, because the keys to the appropriate room were hard to locate. *SNIP Well I went down to the basement and lo and behold, a UPS! It also appeared to be connected to the right equipment too (although i adopted a strictly stand back and look approach so I couldn't be sure that the wires were connecting to the right places given they were hidden inside conduit). Whether or not it is working sufficiently I won't be able to tell but as 'luck' would have it there is a scheduled power outage later this month and I will have a chance to assess whether the problem lies here, or hidden somewhere else along the way. ##################################################################################### This e-mail message has been scanned for Viruses and Content and cleared by MailMarshal #####################################################################################
