SUI Network suffers three outages in 48 hours, price plunges to critical $0.90 support! What does this mean for investors?

From May 28 to May 30, the Sui Network mainnet experienced three separate interruptions in block production due to a software bug. As technical issues mounted, pressure on the SUI price intensified, pushing the token to a crucial support level at around $0.90.

Three Major Outages After the Upgrade

The Sui development team recently upgraded the mainnet to version v1.72. The update introduced an “address balances” feature that conflicted with the network’s transaction fee calculation system. This technical incompatibility caused block production to come to a complete halt during an epoch change.

Following the upgrade, Sui Network encountered three mainnet outages. The team confirmed that the issue stemmed from the new “address balances” function clashing with the existing gas system. The network has resumed normal operations, and no user funds were lost.

Developers responded swiftly, deploying emergency fixes within 48 hours. Once validators implemented the updates, Sui mainnet restored full functionality as of May 30. This marks the second major mainnet outage for Sui in 2026—both directly linked to software upgrades.

Quick glossary: A validator is a participant in a blockchain network who verifies the accuracy of transactions and helps produce new blocks. Sui Network is a blockchain infrastructure focused on enabling decentralized applications.

SUI Price Faces Intensifying Pressure

The outages had an immediate impact on SUI price. The token slid below $0.89, hitting its lowest point in the current cycle. SUI has suffered a 37% drop over the past 20 days, with the sharp decline triggered by both technical stop-loss orders and negative sentiment-driven selling.

Roughly $2 million in long positions were liquidated during the price plunge. On the SUI/USDT daily chart, the token hovered just above $0.90, registering a 0.65% loss in the most recent session.

SUI remains below the $1.1381 Fibonacci retracement level, signaling that much of the previous rally has been erased.

Technical Charts Point to Ongoing Weakness

Overall, SUI is still facing technical headwinds. The token trades far from its previously tested $4.08 region. Short-term resistance levels lie at $1.00 and $1.1381, both of which SUI has struggled to reclaim. Recent attempts to rebound have stalled between $1.10 and $1.25 before being rejected.

Immediate support is located in the $0.85 to $0.90 range. Should SUI dip below $0.85 on a daily close, the next possible target would be in the $0.75 to $0.80 band. On the upside, resistance sits at $1.00 and $1.1381, while much stronger barriers await at $1.7674, $2.2614, and $2.6084—levels that remain relevant only if $1.14 is decisively broken.

Technical indicators reinforce the bearish outlook. The MACD is below zero, underlining a weak market trend. The RSI sits at 36.63, reflecting low demand but not yet heading into oversold territory.

In the short term, stabilizing effects from the latest updates and strong technical support could ease some selling pressure. However, the risk of recurring outages remains a key issue closely watched by investors.
