Now, down to a virus:
Hey Chummers, it's your friendly grid oracle again, this time with news from my home ground.
pueblo Grid Advisory - 838
The following malicious traffic has been observed on several local telecommunication grids: Choker.A, Choker.B, and Choker.C. These three files are currently accounting for 3% of all traffic from the business grind, and 14% of all traffic on the municipal grid. Although this virus does not appear to threaten data, it's spread is causing a noticeable slowdown in some networks. It is recommended that all users update their anti-virus definitions to account for this recent development, repeated failure to fix your systems will result in your commcode being blocked.
