[SAC] Fwd: Re: OSL VLAN 113 Question

[Alex Mandel]

I got this question from OSUOSL today. Anyone want to look into how much
actual data is being served and what it is on download.osgeo?

Thanks,
Alex

Alex,

The report NERO provided us suggests that OSGEO is pushing about 8 TB
of traffic in the 8 days of the report:
Top 10 Src IP Addr ordered by bytes:
Date first seen          Duration Proto       Src IP Addr    Flows(%)
   Packets(%)       Bytes(%)         pps      bps   bpp

Does this seem realistic? Your awstats chart claims about 100G a month.

Network usage on this VLAN is getting saturated, to the point that
pingdom checks are timing out for HTTP services on occasions where
thresholds are crossed.
