We're scheduling a maintenance window 2021-07-26 to 2021-07-30, in order to perform maintenance on our network edge locations. During this window will update the router software, apply a new security ACL, then implement additional firewall and rate-limting rules. We will work on one router at a time, when its traffic is statistically lowest. Please expect a brief period of interruption (typically 5-30 seconds) as BGP routes update around the edge location that you connect to.
