Network access is blocked for projects by default. Go to project settings and click "Adjust quotas", then click the checkbox next to Network. (Background: Until 2 weeks ago, network access from SMC to a large whitelist was allowed. But then people finally started using SMC to blatantly launch DDOS attacks. At Univ of Washington, such attacks would mean an inconvenience as UW shut off network for one node; in contrast, at Google it means all SMC goes down as Google automatically throttles the entire project into oblivion (including the disk.. Or, if they don't, then the DDOS attack costs a lot in terms of egress bandwidth charges.) > > Bill. > > On Monday, 1 February 2016 16:37:13 UTC+1, William wrote: >> >> On Mon, Feb 1, 2016 at 7:32 AM, Dima Pasechnik <[email protected]> wrote: >> > Are Intel(R) Xeon(R) CPU @ 2.30GHz interesting for you? >> > (That's what one gets on SMC.
